  • MacBook Air: USB Hub Compatible with the MBA SuperDrive

    - by _ande_turner_
    A little background to those whom may think this Question to specific: The MacBook Air SuperDrive draws 1A vs 500mA of a normal USB device, and therefore you can't use a standard USB hub powered or unpowered because each port gets 500mA not 1A... Have any MacBook Air users found a USB hub which can accommodate the MBA SuperDrive and another peripheral?

  • Nexus One USB freezes Vista SP2 Quad Core

    - by user25479
    My Nexus One (N1) will occasionally freeze my Vista 32bit SP2 Quad Core 2.4GHz during POST. MB is ASUS P5N-E SLI with 4GB of RAM. The PC will be booting and when I connect the N1 via USB, the boot sequence will freeze, then continue once I unplug the N1 USB link. It happens whether the N1 is in USB debugging mode and when it is not. I'm not sure whether this is an N1 hw/fw issue, system interaction with my PC, or a result of my N1 development environment (I'm using the Eclipse Galileo IDE for Java Developers, primarily compiling to API Level 7. Eclipse has also occasionally frozen although I haven't established N1 USB cause-and-effect on that issue). Is anyone else experiencing these symptom?

  • Using Virtualbox USB capabilities

    - by Eder Gusatto
    Is there anyone actually using the USB capabilities of the Virtualbox? I've tried in 3 diferent computers and just keep receiving the message that the USB device is busy with a previous request. I'm trying to access USB stuff since the first version (now using 3.0.4) but I was never successful. Is there any special configuration or tweak to make?

  • Short USB cables not charging?

    - by tropolite
    I find this a strange problem but I can't find anything online about it. Recently I purchased a few short USB cables (20-30cm), to use in my car's USB connector to charge my phone. Strangely an older longer USB cable (1.2m), charges the phone fine (and the icon changes to show charging). With any of the short cables in the same USB slot no charging happens. Both the long and the short cables are USB2 compatible. I naturally assumed the short cables were faulty but connecting them to a PC or connecting to a high capacity external battery charging is successful using all the short cables and longer cables. Hopefully someone here is able to give me an explanation of the problem and how I can overcome this and use a short cable where it is most appropriate. Thanks

  • None of usb-controllers are working after a crash

    - by Cray
    So I have a GA-p35-DS4 mboard with a Q6600, running windows7-x64. After a random crash with a bluescreen (not caused by anything particular as I recall), none of the usb-controllers are working. (And none of the devices connected to those usb ports). All the controllers are showed up in the device manager, but every one has a warning-icon (as they are not functioning properly). The windows identifies them correctly, it shows exactly the model of each controller, and it says that the driver is installed. Now, when I try to reinstall the driver (Update driver menu item in the device manager), it tries to find it, finds the driver, but quits saying that the driver was found but could not be installed. Additionally, it displays "This operation requires an interactive window station", whatever that means... Now get this, the same thing happens with a new pci-usb controller card! It is found (actually each time the machine starts, it is found as new hardware), but trying to install drivers leads nowhere, I am getting the same message about an interactive window station. (tried to install drivers from the acoompanying CD) I have tried deleting those devices from device manager and let windows find them again, but that leads to same results. None of the ports on this extension card work either. This should not be a hardware problem, a usb keyboard connected to the builtin usb controller works in bios, and even in another OS running the same computer (old xp installation) What to do? Will I have to reinstall? Can deleting infcache.1 help? Is there some way to let windows remove all old drivers and try to find all hardware again, this time only looking for drivers on a windows install disk or something?

  • Kickstart based installation of RHEL 6.4 from USB

    - by Peter
    I want to setup some brand new servers with RHEL 6.4. Servers do not have DVD, so, I have to use USB for the installation. I already have a custom ISO with a kickstart file that I use on servers with DVD flawlessly. I used iso2usb to move the ISO t? my USB. When I boot from the USB, the ks file is found, anaconda starts, but then stops with the following error: "The installation source given by device ['sda1'] could not be found. Please check your parameters and try again" Notes: The USB IS the sda. My custom ISO file is renamed to linux.iso from iso2usb and it is present in the root directory of the USB. Kickstart file has the following entry: harddrive --partition=sda1 --dir=/ Please help me to automate the installation with kickstart.

  • Internet Connection not working - USB LAN connection - from particular modem

    - by Paul
    I am trying to fix Internet connection on a friends Dell inspiron 1720 with XP service pack 3. It has an integrated network card that stopped working, after powering down/up the modem still didnt work I brought it back to my place to try a few things ie check cable, update driver etc... still didnt work. So I bought a USB LAN connector. It didnt work straight away but I went to configure the properties and changed the ConnectionType from AutoSense to 100 BaseT 10BaseT Full_Duplex, I basically just tried them all. From my place when connected to my desktop - 10 BaseT and 10BaseT Full_Duplex worked. From my place When connected to their laptop - 10 BaseT and 10BaseT Full_Duplex worked. Happy I went back to my friends house confident it would all work, and it didnt. Brought it back to mine and it did. While there, in Network Connections the connection is there recognized, enabled, 'working properly' it just says not connected. Also there is no led on the USB connector While at mine as above except there is an led on the USB connector and it says connected. Other difference I can think of is they have a cable modem, I'm plugged into the back of a Belkin wireless router - would this make a difference? Any other ideas what to try? (Would getting the model of the cable modem help anyone?) The USB connector is "DM9601 USB to Fast Ethernet"

  • USB-Powered Speakers

    - by Jonathan Sampson
    I use a set of external USB speakers at the office which have no power-source other than my laptop USB port. Sometimes they're silent, and at others it sounds like an electric moth is fluttering around inside one of the speakers (the main speaker). This doesn't happen when my machine is doing any heavy crunching, it just comes and goes. This has happened with other USB speakers on other laptops too in my experience. Any idea on what causes this, and how I can fix it?

  • USB drivers installed twice

    - by stupid-phil
    Hello, I have a problem with usb drivers on Windows 7 64bit When I start up my laptop, the mouse I have plugged into a usb port does not work. I have to open the device manager, where there are two "Standard Enhanced PCI to USB Host Controller" entries. One is marked as faulty (yellow triangle). I uninstall this. Scan for changes. Then it re-appears, but not marked as faulty. And the mouse works. I have to do this every time I reboot. A colleague has the same problem. Both DELL laptops, but different models. I've tried uninstalling all USB controllers, but after a reboot, they are all reinstalled with the faulty entry. This only started happening in the last few weeks. Any help appreciated. It's driving me nuts. Thanks Phil

  • Non-USB powered laptop cooling pad?

    - by Andrei Rinea
    On my laptop (el-cheapo but pretty good) I have all my 3 USB ports occupied by devices in use (external mouse, external keyboard, 3G internet/flash drive/external hard drive/etc). I want a cooling pad for my hard-worked laptop but all seem to be powered by USB... This laptop is mainly stationary. Either is available a solution to power the USB-powered cooling pad other than connecting it to the laptop... ... either is there a non-USB powered laptop cooling pad?

  • Diagnosing a BSOD involving USB

    - by David Ebbo
    [Running Win7 Ultimate 64 bit] My new HP Pavilion Elite HPE-450t has been plagued by BSDO crashes since I got it about 5 weeks ago. The crashes are somewhat rare, sometimes not occurring for 3 or 4 days. I have spent a lot of time trying to isolate the device that could be at fault, but I have seen crashes with only the keyboard and mouse plugged in (as USB devices), and I tried two sets of keyboard/mouse, so I'm running out of ideas. :( The WhoCrashed tool gave this info about my latest BSOD: crash dump file: C:\Windows\Minidump\121310-11887-01.dmp This was probably caused by the following module: usbport.sys (USBPORT+0x2DE4E) Bugcheck code: 0xFE (0x5, 0xFFFFFA8008F571A0, 0x80863B34, 0xFFFFFA80092F2510) Error: BUGCODE_USB_DRIVER file path: C:\Windows\system32\drivers\usbport.sys product: Microsoft® Windows® Operating System company: Microsoft Corporation description: USB 1.1 & 2.0 Port Driver Bug check description: This indicates that an error has occurred in a Universal Serial Bus (USB) driver. The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system which cannot be identified at this time. I looked at http://msdn.microsoft.com/en-us/library/ff560407(VS.85).aspx, and for Parameter1 = 0x5, it says "A hardware failure has occurred due to a bad physical address found in a hardware data structure. This is not due to a driver bug". Should I conclude that it's a hardware issue in the machine itself, rather than a bad USB driver or USB device? Here is the MiniDump, in case someone can get more info out of it: http://ewt52q.blu.livefilestore.com/y1peS4Ce8nSK1SXghzMDoxDWXlaEu-EKCJsv25y8y5DXXIUzZ9U0_tYgFJXd939fykwa0zRmx98IW0PYG18GioqKAuARYjtspSA/121310-11887-01.dmp?download&psid=2

  • SATA Blu-Ray drive not detected via USB adapter

    - by LTR
    I'm using an SATA blu-ray drive (Lite-On IHOS104), connected via a USB adapter to my Windows 7 (32-bit) notebook. The first time I plugged the adapter in, it worked perfectly. The drive appeared in Explorer, and my player software was able to play an encrypted Blu-Ray disc just fine. After the first reboot, it never worked again. Now it shows up as "removable media" with a size of 0 bytes, irregardless of whether a disk is inserted or not. The drive does not show up under the green "eject USB device" icon in the taskbar. The adapter is powered using a separate power adapter. I have tried: disconnecting all other USB devices testing with a DVD instead of a Blu-Ray disc letting Windows search for updated drivers for the drive - there are none using the same drive and adapter on another Win7 (but x64) computer. They work perfectly. using other USB ports on the same notebook - tried them all. using a different SATA/USB-adapter What else can I do to diagnose this problem?

  • Logitech USB headphones detected and selected in Debian Squeeze but sound still coming from speakers

    I have a pair of Logitech wireless USB headphones that work with Ubuntu Natty but aren't working in Debian Squeeze.

Then I change it to "Output: ALSA Audio output" and a Device menu appears. I select the headphones. When I then save the prefs, the audio switch to the headphones! But here's what's weird: I go back to prefs, change it to "Output: Default" and the headphones keep working. Maybe the ALSA option is actually what is being chosen as the "Default" option, but the Device menu (whose selection is still being used) is still set to the headphones. Anyway, now I need to figure out how to make it work as the default for the whole system.

  • Targus USB-to-RS232 not working with Linux?

    - by Ethan Leroy
    I have the Targus PA088 USB to RS232 converter, but it seems that it does not work with linux. Its RX and TX lights are flashing, but I can't see the data in minicom/picocom. When using it with Windows and hterm, everything's fine. Any idea what could be the problem? Additional info: When I plug in the adapter, I can see the following messages in /var/log/messages.log Nov 25 01:47:31 localhost kernel: [ 831.787066] usb 2-1.1: new full speed USB device number 5 using ehci_hcd Nov 25 01:47:32 localhost kernel: [ 832.554810] mct_u232 2-1.1:1.0: MCT U232 converter detected Nov 25 01:47:32 localhost kernel: [ 832.555002] usb 2-1.1: MCT U232 converter now attached to ttyUSB0 Nov 25 01:47:32 localhost mtp-probe: checking bus 2, device 5: "/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1" Nov 25 01:47:32 localhost mtp-probe: bus: 2, device: 5 was not an MTP device

  • recovering USB printer

    - by shodanex
    I have an USB printer, that was discovered and installed properly. At some point, I suppressed it in the printer view of the config panel. If I try to add a new local printer, it says : Only use this option if you don't have an USP printer ( Windows automatically installs USB printer). How can I make windows automatically reinstall the USB printer I accidentally suppressed ? Edit : It is a dell all-in-one 920 printer, and I just tried to download and reinstall dell software.

  • How to create a bootable USB Windows OS using Mac OS X

    - by Ali
    I'm having a trouble here because of my PC infected today and I tried everything to get it back and the only option left for me now is to do a clean install. Now what happen is I have Macbook Pro with 8GB USB which I emptied the USB stick now. I've download Windows 7 from my college website [With license not pirate] and wanted to make a bootable USB so I can format my PC to get it run again. Now I know that disk utilities can be done with DVD/CD but what I can make a bootable USB to run it on my PC?

  • Asus K55VM usb 3.0 issue

    - by user2141481
    Good day superusers! I own the above laptop and I found out that there are some unknown and unusual issues with usb 3.0 ports. I haven't noticed anything strange until now. I got a new toshiba usb 3.0 external hdd and when I try to copy larger amount of data from my disk to the external hdd, the OS(windows 7) randomly starts ignoring the external hdd. It doesn't shut it down, it kinda just stops responding but the light on the hdd is still lit. I get an error that the files cannot be copied. I have reinstalled windows 7, installed all drivers(including intel chipset drivers of course) and the issue is still present. It acts normal when copying small amount of data. Also, I heard that some intel chipsets have an issue with usb, something about the connectors not transferring power when the usb device enters some kind of "low power mode" causing the device to stop responding and you need to plug it out and in again. But the thing is, my Intel® Chief River Chipset HM76 is not on the list of affected hardware(not ENTIRELY sure though). If anyone has any idea of what the problem to this might be, I'd be greatful. Edit: The hdd works perfectly fine even for large amounts of data if plugged in the usb 2.0 port!

  • How do I create an MBR on a USB stick using DD command line tool

    - by Lana Miller
    Okay I'm trying to create a BOOTABLE Windows7 image on a USB key from a Mac running Lion. My image is .iso format. I tried: sudo dd if=/Users/myusername/Win7.iso of=/dev/disk1 bs=1m And this succeeded in writing the files, except in DISK UTILITY on the mac, it shows the partition type as GUID Partition Table and not 'Master Boor Record'. Booting the key on my Vista computer yields the error "No boot sector on USB Device' From what I can tell, bs=1m in the DD command should have left 1 Megabyte for the boot sector, but for some reason this area of the USB Key is not set up correctly so that it will boot How can I fix this, or correctly use dd to write a bootable cd image such that it is now a bootable usb drive? Note: in the instructions I read about, they recommended renaming my Win7.iso to Win7.dmg before using DD, which made absolutely no sense to me, so I didn't do it. I could try with that step now, but it takes 1.99 hours to write the image to the USB drive so there is a huge penalty to trial and error here. Thank you.

  • USB stick appearing as hard disk drive, not removable storage device

    - by Paul Lammertsma
    I just plugged in a very simple 1GB USB stick from the office in hopes of making it a Fedora Live USB stick. For that to work, I need a removable storage device, or else it won't appear in LiveUSB Creator's list. Explorer lists my USB stick as a hard disk: LiveUSB Creator indeed doesn't show it in the device list: Is there any way of forcing Windows to see the stick as a removable storage device?

  • USB Adapter for Memory Cards

    - by ktm5124
    I am looking for something like a USB adapter for video cards. It is a cable that on one end hooks into a USB port on a computer and on the other accepts any one of a variety of video cards. Essentially it's an "all-in-one" USB adapter for video cards. I'm told that they are sold all over... does anyone know what it is called or where to find them? I should clarify, by the way, that by "video card" I mean a memory card for a video camera, and that the goal is to read this video data onto a computer, from a variety of video card types, through a USB port. That way if you go to your friend's house and bring your computer, you can transfer the video data on his video camera to your computer, trusting that the adapter will have a slot for his kind of video card.

  • How to mount a USB thumb drive as "Fixed" instead of "Removable"

    - by AMissico
    I have over 8 GB in my "Code Library" that I maintain on a 64 GB ScanDisk Ultra Backup USB Device. Windows Search 4.0 (installed on Windows XP) can index removable drives, but Windows 7 (which uses Windows Search 4.0) cannot, because the USB device identifies itself as a Removable drive and Windows 7 refuses to index removable drives. How can I mount the USB Thumb Drive as Fixed instead of Removable?
