  • USB 3.0 hub; what can it power?

    - by pouzzler
    I own an Asus UX31A laptop, equipped with 2 USB 3.0 ports. I would like to connect several USB devices to one of these ports, using a USB 3.0 hub. 1) Am I correct in assuming the Asus "USB Charger+" commercial blurb corresponds to the USB 3.0 standard "Battery Charging Specification 1.2", and furthermore inferring that the laptop can deliver 1.5A through a USB port? 2) Does a powered external USB 3.0 hard drive draw on the USB power lines? 3) I would like to connect the aforementionned drive, an android phone, and a 200mA rated optical mouse to an unpowered USB 3.0 hub, itself plugged into the laptop. Should my above assumptions be false, would this setup be able to power all three devices? Thanks to the usb guru who'll settle my fears to rest. Best regards, Sébastien

  • Redirect outbound traffic on port 53 to port 5300 with iptables

    - by Zagorax
    I'm running a local dns server on port 5300 to develop a software. I need my machine to use that dns but I wasn't able to tell /etc/resolv.conf to check on a different port. I searched a bit on google and I didn't find a solution. I set 127.0.0.1 as nameserver on /etc/resolv.conf. Could you please tell me how can I redirect outbound traffic on port 53 to another port? I tried the following but it didn't work: iptable -t nat -A PREROUTING -p tcp --dport 53 -j DNAT --to 127.0.0.1:5300 iptable -t nat -A PREROUTING -p udp --dport 53 -j DNAT --to 127.0.0.1:5300

  • Install Problem (Ubuntu Server 10.04) with USB as it reboots when I hit 'enter' for 'Install Ubuntu Server' option! Help

    - by Alastair
    We cannot seem to install Ubuntu Server with USB as it reboots when I hit 'enter' for 'Install Ubuntu Server' option. My friend wants to try setting up a server so; we downloaded Ubuntu Server 10.04.4 we created a boot CD and installed ubuntu server no problem at all. But then the problem arose the hardrive we wanted to use is a 1tb sata drive and the computer orginally has 40gb IDE. So I bought a Sata to IDE and IDE to Sata converter from: http://www.microdirect.co.uk/Home/Product/52926/IDE-to-SATA-converter---Converts-IDE-HDD-to-SATA-inc-sata-data-and-power-cables Unfortunately this converter means I cannot plug in the IDE cable meaning I only have one IDE connection i.e CD drive has to be disconnected for the 1tb sata Hardrive to be connected. So now the 1tb drive is connected, powered it on opened the bios to make sure the hdd appeared it did as ST3ASDAPFKG (somthing like that). Fortunately the computer supports USB booting, so I read ubuntu server usb install instructions I tried: Startup Disk Creator & Unebootin Startup Disk Creator made the usb bootable with the 'ubuntu-10.04.4-server-i386.iso' All looked fine stuck the usb drive in, booted the machine up and I am quickly presented with ubuntu language choice. I hit enter to select English then I am presented with: Install Ubuntu Server, Install Ubuntu Enterprise Cloud, Check Disk for defects, test memory, Boot from first hard disk, Rescue a broken system I can move up and down the menu fine everything seems ok, I select 'Install Ubuntu Server', computer just hangs and screen either goes blank or locks. So I rebooted the computer loads the same menus fine, I select 'Install Ubuntu Server' hit 'enter' and the computer just restarts then brings me back to the same menu. hmmm Then I tried choosing the rest of the options separately: Install Ubuntu Server, Install Ubuntu Enterprise Cloud, Check Disk for defects, test memory, Boot from first hard disk, Rescue a broken system computer just restarts and back to the same ubuntu menu every-time. Grrrr At this point I wish I actually new how to command line install or something but I don't have a clue how to do that. So I tried hitting 'f6' for 'other options' and I tried them all in various combinations and individually. No Luck: (Expert mode, acpi=off, noapic, nolapic, edd=on, nodmraid, nomodeset, Free Software only) At this point I am wondering if it is a bios setting causing problems, I tried turning every option in there on off that I don't understand. No Luck. I then discovered by accident if you hit esc in the ubuntu install menu it says "you are leaving the graphical boot menu and starting the text mode interface" I hit 'Ok'. Next a prompt pops up saying 'boot:' One time it responded when I typed somthing with 'Cannot find kernal image (something like that but since then it just restarts when I hit enter in that prompt). I had a browse on the net and found someone suggesting removing quiet from install command for 'Install Ubuntu Server'. Made no difference at all just reboots... Orginal boot options noprompt cdrom-detect/try-usb=true persistent file=/cdrom/preseed/ubuntu-server.seed initrd=/install/initrd.gz quiet -- Modified boot options noprompt cdrom-detect/try-usb=true persistent file=/cdrom/preseed/ubuntu-server.seed initrd=/install/initrd.gz -- Still I cannot install Ubuntu Server by USB as it, reboots when I hit 'enter' for 'Install Ubuntu Server' option. This is a real pain as we cannot take the 1tb Sata Hardrive and swap it for IDE to be able to use the cd drive. Why is is it so hard to install ubuntu server with usb? I have wasted a full day and half on this really frustrated any help would be amazing! I know the answers out there just seems a bit illusive at the moment! Computer Spec- Asus Motherboard, 1gb RAM 2X512MB, Powersupply 200watt, 2.8ghz Processor Intel, On-board 64mb graphics, 100mb Ethernet, 54mb Wireless,

  • Anything such as a usb laptop charger?

    - by iNinja
    I am looking for a laptop charger that requires no power outlet but instead utilizes a usb port of another computer to charge my laptop. That is, I am seeking a usb-to-laptop port charger, NOT power outlet-to-laptop's usb charger. Is such a product even possible? I am guessing no since the usb port would not be able to supply enough electricity to power the laptop, even to maintain the battery (not charge it).

  • Port forwarding + shared connection with Ubuntu

    - by Joey Adams
    Because my wireless router's ethernet ports are defective, I set up a shared wireless connection from my laptop (which has wifi) to my eMac (which does not) via a crossover ethernet cable. The laptop is behind a router as 192.168.1.131, and the eMac is behind the laptop as 10.42.43.1 . The laptop is running Ubuntu 9.10 (Karmic). I achieved the shared connection through NetworkManager Applet. I right-clicked on the network icon at the topright, went to Edit Connections, selected the Wired connection named "Auto eth0", clicked "Edit...", went to the "IPv4 Settings" tab, and selected the Method "Shared to other computers". The eMac can now access the Internet. Now I want to enable port forwarding. There's a game I want to play that needs port 6112 forwarded (both TCP and UDP) in order to host games. I set up the router to enable port forwarding for 192.168.1.131 (the laptop), but port forwarding still isn't available on the eMac. I suppose I need to pretend my laptop is a router and configure port forwarding on it, indicating that incoming connections to the laptop (192.168.1.131) should be forwarded to the eMac on the shared connection (10.42.43.1 ). Thus, packets coming into the router on port 6112 would be redirected to the laptop (by the router), then to the eMac (by the laptop). My question is, how would I do that on Ubuntu (in light of NetworkManager's presence)? Also, if I can't get this to work, does anyone mind hosting a comp stomp? :D

  • SSH dynamic port forwarding, "Connection refused"

    - by crodjer
    I am trying to do dynamic portforwarding using openssh through a remote computer following this command: ssh -D 6789 rohan@<remote_ip> -p <remote_port> This should set up a socks server on my comp as I assume. I am able to use this for normal browsing but can't connect to IRC or remote ssh (through proxychains).

  • Linux Port 80 to redirect to a Windows box

    - by Richard Staehler
    I have 2 servers here at work. One is a Windows 2008 Server R2 (for safety's sake, lets use 192.168.1.100) and the other is a Fedora 14 (192.168.1.101). Currently when you hit our subdomain, x.test.com, our routers tell it to go to our Fedora box, and since Apache is installed and listening to port 80, it displays the Fedora Apache Test Page. It's obvious that I don't use port 80 for this machine, however I do use NAGIOS on it and its always nice to be able to access that from anywhere in the world. So when I want to access it, I just type x.test.com/nagios. Now here comes the dilemma.... On the Windows R2 box, we recently have installed a program that requires us to setup a web server using IIS7. Because of this application, I'm going to be creating a new subdomain called y.test.com, but since we only have 1 WAN/router, it will still get pointed to our Fedora box. That being said, it wants to use port 80 as well (or whatever port I damn well wish to assign it). So my question is: since our router is pointing to the Fedora 14 box (.101), and I want to make sure I can access NAGIOS from anywhere in the world, how do I tell Apache (httpd) to redirect port 80 to the other server (.100)? If not possible, what are my other options? I have rinetd installed on Fedora and have even tried the option 192.168.1.101 80 192.168.1.100 80 and it didn't seem to work "because port 80 was already bound" Thoughts? and Thanks!

  • .htaccess redirect to error page if port is not 80

    - by Momo
    I'm running a portable server through usb stick. The thing is I also have WAMP installed in my local machine and Apache somehow gets started on windows startup, because of some random reason which I don't recall now and it can't be changed. I want to prepare my portable server in situations like this, so closing httpd.exe from process and starting my portable server is not an option. Anyway, because of already active httpd.exe my portable server's WordPress site can only be accessed through localhost:81 - this is a problem as WP site is very dependent on the URL and I don't want to include the url with port on WP database. Here is what I want to do through .htaccess: On any path except for error.php file check if not port 80 If not port 80 redirect to /error.php?code=port It it possible for it to have priority over WP redirection or URL handling? In the error.php I provided info on how to manually close httpd.exe and such so my family and friends can access the portable site. It's sort of like a gallery and calender application for events and other such stuff... Please help? I'm I can't figure it out at all. I know others may not have apache already running, but I want to prepare for such a situation. Something like the following, but the following doesn't work. # BEGIN WordPress <IfModule mod_rewrite.c> <If "%{SERVER_PORT} = 80"> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </If> <Else> RewriteEngine On RewriteRule ^(error.php)($|/) - [L] RewriteRule ^(.*)$ /error.php?code=port [L] </Else> </IfModule> # END WordPress By the way, the portable server Server2Go automatically generates vhosts based o the hostname set on it's config file and changes ports if the port (e.g. 80) is already open.

  • Setting up port forwarding for web server

    - by reyjavikvi
    This could belong on Super User, but I thought this place was more appropiate. I want to run Apache in my computer and want to make it available to the outside world to test a couple things. Apparently, I have to go into my router's (a TP-LINK TD 8910G) settings and forward port 80 to my PC's IP. So far so good. Thing is, since the router uses a web based interface and it's kind of stupid, it told me that since I was using port 80 for this, I should access its settings through port 8080. Maybe it can't detect requests coming from the LAN, I don't know. Point is, now neither port can't access the configuration, and I can't access Internet. Specifically, trying to access anything (including 192.168.1.1, the router's settings) through port 80 turns up a blank page (maybe if I had the server running in my computer I'd get something, but I don't want to risk trying, I had to reset the router and restore the settings), and port 8080 gives a "Can't establish connection" error in Firefox (and similar ones in other browsers). Is there a way to configure the router to not redirect requests coming from inside the network? I'm a beginner with this stuff, so please try to explain in a simple way. If this is more appropiate in Super User, I'm sorry.

  • port forwarding problem

    - by Claudiu
    I want to set up an svn server on my computer, so it's available from anywhere. I think I set up the repository correctly, using CollabSVN. If I go to Repo-Browser with TortoiseSVN and point it to svn://localhost:3690, it shows the proper repository. The problem now is that I'm behind a router. My local IP is 192.168.1.45 . Doing svn://192.168.1.45:3690 also works. My global IP is, say, x.x.x.x. Just doing svn://x.x.x.x:3690 doesn't work, which makes sense, since I have to set up port forwarding. I'm using a Verizon router. Using their web interface (on 192.168.1.1) I added the following port forwarding rule: IP Address forward to: 192.168.1.45 Source Ports: Any Dest Ports: 3690 Forward to: 3690 Protocol: TCP However, even after applying this rule, going to svn://x.x.x.x:3690 doesn't work. It takes a few seconds to fail, then says that the connection couldn't be established because the server connected to didn't respond properly after a period of time. What's interesting is that a random port, like svn://x.x.x.x:36904 fails immediately, saying that the target machine actively refused the connection. So I figure that the forwarding rule did something, but not fully what was necessary. Any ideas on how to get this working? The router model is MI424-WR and the firmware version is 4.0.16.1.56.0.10.12.3. UPDATE: I also tried setting destination port to 45000, and still forwarding to 3690, in case something was wrong w/ the lower-numbered ports, but to no avail. I also tried port 80 to port 3690, still all in vain.

  • Howto disable SSH local port forwarding ?

    - by SCO
    I have a server running Ubuntu and the OpenSSH daemon. Let's call it S1. I use this server from client machines (let's call one of them C1) to do an SSH reverse tunnel by using remote port forwarding, eg : ssh -R 1234:localhost:23 login@S1 On S1, I use the default sshd_config file. From what I can see, anyone having the right credentials {login,pwd} on S1 can log into S1 and either do remote port forwarding and local port forwarding. Such credentials could be a certificate in the future, so in my understanding anyone grabbing the certificate can log into S1 from anywhere else (not necessarily C1) and hence create local port forwardings. To me, allowing local port forwarding is too dangerous, since it allows to create some kind of public proxy. I'm looking for a way tto disable only -L forwardings. I tried the following, but this disables both local and remote forwarding : AllowTcpForwarding No I also tried the following, this will only allow -L to SX:1. It's better than nothing, but still not what I need, which is a "none" option. PermitOpen SX:1 So I'm wondering if there is a way, so that I can forbid all local port forwards to write something like : PermitOpen none:none Is the following a nice idea ? PermitOpen localhost:1

  • Ask How-To Geek: Learning the Office Ribbon, Booting to USB with an Old BIOS, and Snapping Windows

    - by Jason Fitzpatrick
    You’ve got questions and we’ve got answers. Today we highlight how to master the new Office interface, USB boot a computer with outdated BIOS, and snap windows to preset locations. Learning the New Office Ribbon Dear How-To Geek, I feel silly asking this (in light of how long the new Office interface has been out) but my company finally got around to upgrading from Windows XP and Office 2000 so the new interface it totally new to me. Can you recommend any resources for quickly learning the Office ribbon and the new changes? I feel completely lost after two decades of the old Office interface. Help! Sincerely, Where the Hell is Everything? Dear Where the Hell, We think most people were with you at some point in the last few years. “Where the hell is…” could possibly be the slogan for the new ribbon interface. You could browse through some of the dry tutorials online or even get a weighty book on the topic but the best way to learn something new is to get hands on. Ribbon Hero turns learning the new Office features and ribbon layout into a game. It’s no vigorous round of Team Fortress mind you, but it’s significantly more fun than reading a training document. Check out how to install and configure Ribbon Hero here. You’ll be teaching your coworkers new tricks in no time. Boot via USB with an Old BIOS Dear How-To Geek, I’m trying to repurpose some old computers by updating them with lightweight Linux distros but the BIOS on most of the machines is ancient and creaky. How ancient? It doesn’t even support booting from a USB device! I have a large flash drive that I’ve turned into a master installation tool for jobs like this but I can’t use it. The computers in question have USB ports; they just aren’t recognized during the boot process. What can I do? USB Bootin’ in Boise Dear USB Bootin’, It’s great you’re working to breathe life into old hardware! You’ve run into one of the limitations of older BIOSes, USB was around but nobody was thinking about booting off of it. Fortunately if you have a computer old enough to have that kind of BIOS it’s likely to also has a floppy drive or a CDROM drive. While you could make a bootable CDROM for your application we understand that you want to keep using the master USB installer you’ve made. In light of that we recommend PLoP Boot Manager. Think of it like a boot manager for your boot manager. Using it you can create a bootable floppy or CDROM that will enable USB booting of your master USB drive. Make a CD and a floppy version and you’ll have everything in your toolkit you need for future computer refurbishing projects. Read up on creating bootable media with PLoP Boot Manager here. Snapping Windows to Preset Coordinates Dear How-To Geek, Once upon a time I had a company laptop that came with a little utility that snapped windows to preset areas of the screen. This was long before the snap-to-side features in Windows 7. You could essentially configure your screen into a grid pattern of your choosing and then windows would neatly snap into those grids. I have no idea what it was called or if was anymore than a gimmick from the computer manufacturer, but I’d really like to have it on my new computer! Bend and Snap in San Francisco, Dear Bend and Snap, If we had to guess, we’d guess your company must have had a set of laptops from Acer as the program you’re describing sounds exactly like Acer GridVista. Fortunately for you the application was extremely popular and Acer released it independently of their hardware. If, by chance, you’ve since upgraded to a multiple monitor setup the app even supports multiple monitors—many of the configurations are handy for arranging IM windows and other auxiliary communication tools. Check out our guide to installing and configuring Acer GridVista here for more information. Have a question you want to put before the How-To Geek staff?

  • How to make Logitech Anywhere MX work in Ubuntu 12.X?

    - by alfC
    I have a Logitech Anywhere MX mouse (wireless), when I connect it to the computer it doesn't work. The mouse works in other computers with Windows and with Fedora 17, but it doesn't work in two different computers with Ubuntu 12.04 and 12.10.

  • Internal drives vs USB-3 with external SSD or eSata with External SSD

    - by normstorm
    I have a need to carry VMWare Virtual Machines with me for work. These are very large files (each VM is 20GB or more) and I carry around about 40 to 50 VM's to simulate different software configurations for different client needs. Key: they won't fit on the internal hard drive of my current laptop. I currently execute the VM's from an external 7200RPM 2.5" USB-2 drive. I keep copies of the VM's on other 5400 external USB-2 drives. The VM's work from this drive, but they are slow, costing me much time and frustration. It can take upwards of 30 minutes just to make a copy of one of the VM's. They can take upwards of 10-15 minutes to fully launch and then they operate sluggishly. I am buying a new laptop (Core I7, 8GB RAM and other high-end specs). I intend to buy an SSD for the O/S volume (C:). This SSD will not be large enough to hold the VM's. I have always wanted a second internal hard drive to operate the VM's. To have two hard drives, though, I am finding that I will have to go to a 17" laptop which would be bulky/heavy. I am instead considering purchasing a 15" laptop with either an eSATA port or USB-3 ports and then purchasing two external drives. One of the drives might be an external SSD (maybe OCX brand) for operating the VM's and the other a 7400RPM 1TB hard drive for carrying around the VM's not currently in use. The question is which options would give me the biggest bang for the buck and the weight: 1) 2nd Internal SSD hard drive. This would mean buying a 17" laptop with two drive "bays". The first bay would hold an SSD drive for the C: drive. I would leave the first bay empty from the manufacture and then purchase/install an aftermarket SSD drive. This second SSD drive would have to be very large (256 GB), which would be expensive. I would still also need another external hard drive for carrying around the VM's not in use. 2) 2nd internal hard drive - 7400 RPM. Again, a 17" laptop would be required, but there are models available with on SSD drive for the C: drive and a second 7200 RPM hard drives. The second drive could probably be large enough to hold the VM's in use as well as those not in use. But would it be fast enough to drive the VM's? 3) USB-3 with External SSD. I could buy a 15" laptop with an SSD drive for the C: drive and a second hard drive for general files. I would operate the VM's from an external USB-3 SSD drive and have a third USB-3 external 7200 RPM drive for holding the VM's not in use. 4) eSATA with External SSD. Ditto, just eSATA instead of USB-3 5) USB-3 with External 7400 RPM drive. Ditto, but the drive running the VM's would be USB-3 attached 7400 RPM drives rather than SSD. 6) eSATA with External 7400 RPM drive. Dittor, but the drive running the VM's would be eSATA attached 7400 RPM drives rather than SSD. Any thoughts on this and any creative solutions?

  • Serial port access errors in WINE

    - by goldenmean
    Hello, I have a setup in which I use a USB serial adapter + some application which sends and receives data using that serial usb. But this setup which works on a Windows, or even in a VMWare Virtual windows, does not work under WINE. IT transmits data but i cannot receive data. The cable and the applications are same as in the working and non-working scenarios. I guess The fact that the application works over the USB serial cable just as fine under Virtual Windows(VMware running on linux) by mapping /dev/ttyUSB to the com port, no external software/DLL needed, means it does not need any specific driver. (Am I correct in this assumption that application doesnt need any driver?) (I also tried with a different setup(different USB serial adapter + different application under WINE, but even that does not work under WINE, but it works fine under WIndows/Virtual Windows) How can I get it working under WINE? Any pointers appreciated.

  • Cisco IPSec, nat, and port forwarding don't play well together

    - by Alan
    I have two Cisco ADSL modems configured conventionally to nat the inside traffic to the ISP. That works. I have two port forwards on one of them for SMTP and IMAP from the outside to the inside this provides external access to the mail server. This works. The modem doing the port forwarding also terminates PPTP VPN traffic. There are two DNS servers one inside the office which resolves mail to the local address, one outside the office which resolves mail for the rest of the world to the external interface. That all works. I recently added an IPSec VPN between the two modems and that works for every thing EXCEPT connections over the IPSec VPN to the mail server on port 25 or 143 from workstations on the remote lan. It would seem that the modem with the port forwards is confusing traffic from the mail server destined for a machine on the other side of the IPSec VPN for traffic that should go back to a port forward connection. PPTP VPN traffic to the mail server is fine. Is this a scenario anybody is familiar with and are there any suggestions on how to work around it? Many thanks Alan But wait there is more..... This is the strategic parts of the nat config. A route map is used to exclude the lans that are reachable via IPSec tunnels from being Nated. int ethernet0 ip nat inside int dialer1 ip nat outside ip nat inside source route-map nonat interface Dialer1 overload route-map nonat permit 10 match ip address 105 access-list 105 remark *** Traffic to NAT access-list 105 deny ip 192.168.1.0 0.0.0.255 192.168.9.0 0.0.0.255 access-list 105 deny ip 192.168.1.0 0.0.0.255 192.168.48.0 0.0.0.255 access-list 105 permit ip 192.168.1.0 0.0.0.255 any ip nat inside source static tcp 192.168.1.241 25 interface Dialer1 25 ip nat inside source static tcp 192.168.1.241 143 interface Dialer1 143 At the risk of answering my own question, I resolved this outside the Cisco realm. I bound a secondary ip address to mail server 192.168.1.244, changed the port forwards to use it while leaving all the local and IPSec traffic to use 192.168.1.241 and the problem was solved. New port forwards. ip nat inside source static tcp 192.168.1.244 25 interface Dialer1 25 ip nat inside source static tcp 192.168.1.244 143 interface Dialer1 143 Obviously this is a messy solution and being able to fix this in the Cisco would be preferable.

  • Linux USB/Serial port won't create a tty device in /dev

    - by Dave
    I am connecting a USB to serial driver port to my system and I get about halfway to where I need to go. When it is plugged in dmesg indicates: <6>usb 2-1: new full speed USB device using sl811-hcd and address 4 <6>usb 2-1: configuration #1 chosen from 1 choice and lsusb Bus 2 Device 4: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port Bus 2 Device 1: ID 0000:0000 Bus 1 Device 1: ID 0000:0000 I get a series of usbdev2.4 (usbdev2.4, usbdev2.4_ep00, etc) devices in dev but no ttyUSB0 or anything that I can open with minicom. How do I get the system to create the /dev device? Thanks Dave

  • Latitude D600 USB port problem

    - by Moab
    Both USB ports stopped communicating on my D600, they have power, my optical mouse still lights up, no device works on the ports, everything is fine in Device manager in Dual boot XP and W7. Checked the bios, not much in there for USB. No usb device shows up when I use the F12 boot device menu either, so it must be some hardware issue. I have another hard drive with Ubuntu on it, popped it in and USB does not communicate with it either. Appears to have 5v but no communication, any Ideas besides another motherboard or USB card for the pcmcia slot (these don't work to well from my research)? I mostly use them for mass storage devices and pcmcia slots don't supply enough power for these devices. Thanks to all who answer with last ditch efforts. I hate to give up on it, its been good to me and still runs rather well for its vintage. EDIT: I did inspect the ports with a flashlight and did a partial disassembly of the laptop in an attempt to check the solder joints, but would require complete motherboard removal to see them, that is where I stopped. .

  • USB connection is unstable with Nexus S 2.3.4 on AMD 64 running 64-bit Windows 7, but works with 32-bit Windows Vista

    - by Mike
    The USB connection is unstable with Nexus S (Android 2.3.4) on AMD 64 running 64-bit Windows 7, but it works with 32-bit Windows Vista. Problem Description: On the 64-bit Windows 7 machine my Nexus S appears to connect, but then it disconnects moments later. Neither accessing USB storage or loading an Android application package file (APK) using the Android Debug Bridge (ADB) work. On 32-bit Windows Vista using the same USB cable, USB storage works. I haven't tried the ADB on 32-bit Windows Vista. Reproduction steps for USB storage: (I have provided the reproduction steps for USB storage and not ADB, because if one isn't working, then the other isn't working either and the USB storage reproduction steps are shorter to document.) Connect the USB cable to the Nexus S and my Windows 7 machine. Effect: The "USB Mass Storage, USB Connected" dialog appears with the button "Turn on USB storage." Click "Turn on USB Storage" Effect: The "working circle" appears. A dialog briefly appears saying "USB storage in use," then it either returns me to Step 1 (now that I am running 2.3.4) or is replaced with the Nexus S's application homepage (while I was running 2.3.3). I'm not sure if the version matters, but I mention it for completeness. On the 32-bit Windows Vista machine the connection is stable. I am able to navigate through the Nexus S file system create, read, update, and delete files, etc. I haven't tried connecting with the ADB. Troubleshooting summary: Tried and failed: Uninstalling and reinstalling the Android USB drivers including removing the files. Uninstalling my custom software Pulling the Nexus S's battery Restarting the Nexus S Restarting 64-bit Windows 7 Changing USB ports on the 64-bit Windows 7 box Compared the dates and file size on the DLLs in my google-usb_driver\amd64 directory and the windows\System32 directory. They match. The sizes for the google-usb_driver\i386 directory do not match (expected). Turning off Debugging mode on the Nexus S does not resolve the problem. Searching Google. Tried and succeeded: Connecting to another machine (Windows Vista) using the same USB cable and Nexus S phone. Troubleshooting observations: I notice that uninstalling the device drivers and deleting the files, then reinstalling the drivers, then rebooting 64-bit Windows 7 then unplugging the Nexus S, then plugging it back in occasionally helps for a short amount of time (minutes to hours, not days). When it is working, I can both access the Nexus S's drive and load/test applications using the ADB. I have observed some wonky behavior in the Device Manager that I haven't tracked down. Sometimes the black Nexus S image appears in the list of devices. Sometimes the image displays as a computer with a green ISA card. Sometimes it neither appears on the top level of devices nor under “other devices,” but it does appear under "disk drives" as "Android UMS Composite USB Device." System configuration: The Nexus S is running Android OS 2.3.4's "Settings\about phone\System updates" indicates that it is up to date as of May 21st 2011. Both 32-bit Windows Vista and 64-bit Windows 7 are up to date. The Windows Vista system is running on an Intel 32-bit processor. Windows 7 is running on an AMD 64-bit processor. I have done Android development on both systems, but I usually develop on the 64-bit Windows 7 machine.
