  • Backup folder on sometimes attached external usb harddrive

    - by ctrler
    My girlfriend no longer has space her laptops drive to store her photos. The drive she has now is 750GB, so to go to a bigger drive would be expensive, as there isn't many 1.5tb 2.5 inch 9.5mm hdd on the market (as of now, there is only one). Because of that, I am thinking of moving her pictures to a cheap external usb hdd. As of now, I'm automatically backing up her important folders (My Documents, Pictures, etc.) using Windows 7 default backup software to a network drive. My problem is that I don't know of a good solution to automatically backup a folder residing on an usb disk. The usb disk won't be attached to the computer all the time, so I can't just treat it as a normal backup folder. Sometimes the backup would run and the folder would not be there! Anyone knows any software or methodology to backup folders on external usb hard drives that are not always present? Thanks

  • Using multiple USB webcams in Linux

    - by rachelderp
    Running more than one USB webcam in Debian/Linux results in the the following error: libv4l2: error turning on stream: No space left on device VIDIOC_STREAMON: No space left on device What initially seemed to be a programming issue in OpenCV turned into a quest for a mysterious hardware/software problem after the same errors were produced by running cheese and xawtv. Apparently it's caused by webcams requesting all the available bandwidth on the USB host controller. With that in mind I decided to run wireshark and capinfos to see just how much bandwidth a single camera used. 4 megabits per second at 320x240 14 megabits per second at 640x480 32 megabits per second at 1920x1080 Interesting! That might explain why two cameras at 320x240 work but any higher resolution fails. It's as if my USB controller is only operating at USB 1 speeds, yet lsusb shows both webcams belonging to a device which supposedly supports 480 megabits per second. One solution proposed forcing the webcams to calculate their bandwidth usage instead of requesting their maximum by running the following commands: sudo rmmod uvcvideo sudo modprobe uvcvideo quirks=128 Unfortunately that made no difference, so I decided to try another solution. A post on StackOverflow suggested telling my webcams to use a lower FPS or compressed video format like MJPEG, but after running v4lctl list it doesn't appear either of my webcams support changing their video mode. And that's where I'm stuck. Why would two webcams operating well below the maximum speed of USB 2 would produce this error? ps: It's not a disk space issue, df displays no change when the webcams are started. pps: If it makes a difference, here's the output of lsusb

  • USB devices don't work after restoring from Stand By

    - by Steve
    Hi. I'm running Windows XP SP3 on a NEC Versa L1100 laptop. If I wake my laptop up from Stand By, no attached USB devices will function. Device Manager shows all USB entries to be working properly. There is an option to "Allow the computer to turn off this device to save power" in the Power Management properties of USB entries. Is this causing the issue or something else? I have the latest drivers for my motherboard installed.

  • USB drivers stopped working in Windows 8

    - by Maxim V. Pavlov
    I have installed an MSDN version of Windows 8 Professional (x64) RTM. For about 3 restarts everything worked well. But once I've rebooted again - USB drivers (all of them, inluding the USB 3 drivers) stopped working. Device Manager properties said that the USB driver is not compatible with the system. Gigabyte doesn't list Windows 8 drivers for my MB X58A-UD3R. Tried to reinstall windows 7 USB drivers - system said the current driver is fine and didn't want to reinstall. Is this the common Windows 8 problem? How can solve it or debug it even more?

  • Creating bootable Fedora USB with persistent storage

    - by dooffas
    I am attempting to burn the full Fedora 19 x86_64 DVD iso to a USB drive and have a separate partition on it for a kickstart file / other media that will be installed in the kickstart process. With the Ubuntu server 12 iso, you can simply dd the iso to the usb drive: dd if=/path/to/iso of=/dev/sdb Once the iso has been burnt, open gparted and create a ext2 parition in the allocated space. However, this does not seem to work with the Fedora ISO. When loading the USB drive in gparted I get a warning and an error: Warning: The driver descriptor says the physical block size is 2048 bytes, but Linux says it is 512 bytes. Error: The partition's data region doesn't occupy the entire partition. Ignoring both of these errors allows gparted to load the usb drive, however it shows a blank drive with no partition table. Has anyone come across this before? From what I have found, it may have something to do with the fact that Fedora use isohybrid.

  • "Boot Error" message when booting Ubuntu 9.10 from USB sticks (Occurs only on 1 PC)

    - by xeross
    Hey, Since today suddenly both my USB ubuntu installations (2 different USB sticks) try to boot and nothing loads but all I see is a message saying "Boot Error". When I press space it continues booting from the main hard drive. I tried reinstalling ubuntu on the USB stick but same error. This only happens on 1 computer and started happening today, before it worked just fine. Any idea what's causing this ? Regards, Xeross

  • Cheap NAS for connecting a USB drive to the network

    - by olaeld
    I am looking for a cheap way of hooking up a USB drive to the LAN. This could be a router with a USB port, or possibly a more regular NAS device with a USB port. I am hoping to find something below $200. But if there is a device with "magical properties" I may be interested to hear about it anyway.

  • Lenovo Thinkpad T430 not booting from HDD if there is a USB modem connected

    - by user93353
    I have a T430 Levono Thinkpad running Win7. I use a ZTE USB modem (something like this) for my internet connection. I usually keep the modem plugged into the USB drive even when the laptop is shutdown or hibernating. This worked fine on my earlier laptops. But with the Lenovo, my laptop doesn't boot if the modem is in the USB drive. It shows the initial character based screen where it gives the Thinkpad message & BIOS details and then waits. If I pull out the modem, it goes ahead. I have disabled USB as a boot option in my BIOS settings, but even then this happens sometimes (but not all the times). Likewise while resuming from hibernation. The USB modem also has drivers & ISP connection client which getting installed the first time you use it on any machine. I have used multiple laptops (HP, DELL, Acer, Gateway) but never faced this problem before. I have friends who use other Thinkpad models but haven't faced this issue. Any resolutions, workarounds for this?

  • Performance of external USB disk with ESXi5

    - by PeterMmm
    I have a new HP DL120 G7 server with ESXi5. One VM is a Win2003 instalation and I have an external USB2.0 drive attached by USB Controller and USB Device. I copy a 4GB file from external USB to server disk. In the VM that takes up to 10 minutes. On a native Win2003 that takes aprox. 3 minutes. I have no explaination for that diference: In any case the bottleneck is the USB connection, much slower than the disks (SAS, RAID1). If the USB connection on the VM would be USB1.1 and not USB2.0 it would take much more time. (The disk performance between server partitions on the VM is correct. - see update) Could be that my native box is extremely fast and the VM is the normal case. ??? Update I try with passtrough and a first run copy the same data in aprox. 7 minutes. Still 2 times slower than the native connection. I also did another messure and the copy between partitions on the same VM takes 3 minutes.

  • USB 3.0 Device not detected in Windows 8

    - by Tek
    About my setup: Windows 8 64-bit. X79-UD3 Motherboard. Latest Windows 8 USB 3.0 Drivers from motherboard manufacturer website. All right so device manager detects my USB 3.0 ports, so all is well there. However when I plug in my external USB 3.0 hard drive, windows doesn't even make a beep; the hard drive is not picked up by device manager at all. The SAME thing happens with Ubuntu 12.10 BUT adding PCI=nomsi (as a workaround) to the Grub command line of the Ubuntu boot option makes Ubuntu 12.10 detect my external hard drive. I also have a few other doubts, if you guys would be kind enough to answer them that include: Should XHCI hand-off in the UEFI bios be enabled or disabled for Windows 8? The difference between XHCI hand-off and EHCI hand-off and what are it's effects on USB 3.0 functionality? And last but not least how can I get Windows 8 to recognize my external hard drive when Ubuntu 12.10 (after the Grub workaround) works fine?

  • all USB "randomly" disconnect and reconnect

    - by teuneboon
    I'm having a weird issue currently: at seemingly random times(although it seems to happen mostly when USB is used a lot, ie downloading + uploading over my WiFi stick or viewing an HD video from my external hard-drive) all my USB devices disconnect and reconnect after a few seconds. This wouldn't be a HUGE problem if I didn't have to rely on my USB for my internet, because now every time this happens my internet, and with it stuff like remote desktop, crashes. I'm running Windows 8 Pro 64 bit with a Gigabyte 990FXA-D3 motherboard. Now the weird thing: I had the same problem with my previous pc, which had a different motherboard(I think it was an Asus M4A785TD-V EVO). I googled a bit and didn't really find anything about this, only found out I could check if something shows up in the Event Viewer, and I get this error there when the USB crashes: "A timeout occurred while waiting for the EHCI host controller Interrupt on Async Advance Doorbell response." If you require any extra information I'm happy to provide it.

  • How can I keep a folder synchronized to an external USB hard drive in Ubuntu?

    - by Cesar
    I have a growing music collection which I manually keep in sync with an external USB drive. Sometimes I edit their ID3 tags, add or delete a file in either the hard drive or the USB drive, and I would like to keep those changes synchronized between both. Does Ubuntu has something available that would help me with this scenario? Preferably something easy to use with a UI. Update: To clarify my question, changes may happen on both the local hard drive or the USB drive, so the sync process must be on both directions.

  • HashMap key problems

    - by Peterdk
    I'm profiling some old java code and it appears that my caching of values using a static HashMap and a access method does not work. Caching code (a bit abstracted): static HashMap<Key, Value> cache = new HashMap<Key, Value>(); public static Value getValue(Key key){ System.out.println("cache size="+ cache.size()); if (cache.containsKey(key)) { System.out.println("cache hit"); return cache.get(key); } else { System.out.println("no cache hit"); Value value = calcValue(); cache.put(key, value); return value; } } Profiling code: for (int i = 0; i < 100; i++) { getValue(new Key()); } Result output: cache size=0 no cache hit (..) cache size=99 no cache hit It looked like a standard error in Key's hashing code or equals code. However: new Key().hashcode == new Key().hashcode // TRUE new Key().equals(new Key()) // TRUE What's especially weird is that cache.put(key, value) just adds another value to the hashmap, instead of replacing the current one. So, I don't really get what's going on here. Am I doing something wrong?

  • How do I get my mac to boot from an Ubuntu USB key?

    - by Vinay Gupta
    so if you select "mac" and "usb" on this download page, it gives a series of command line instructions to make a USB key which the MacBook will boot into Ubuntu from. http://www.ubuntu.com/desktop/get-ubuntu/download I've followed them to the letter two or three times on different USB keys, and it doesn't work. There's a very great deal of technical discussion about EFI etc. but this set of instructions seems to suggest it should Just Work, and it doesn't. Help? I'm increasingly unhappy with the more locked-down approach Apple is taking, and I'd quite like to start using Linux with a view to transitioning over to using it as my main operating system, but booting from the CD takes forever, runs slowly and I'm really hoping to get it moving off USB. Can anybody help me?

  • How to associate hardware volume control to USB speakers?

  • Can I use Ubuntu to write a Windows 7 ISO to USB in Ubuntu?

    I need to create a Windows installation USB drive from an ISO file. I used unetbootin which seems to be the only tool that can write non-linux images. The USB disk boots (sort-of), but it gets stuck at the very first stage. A UNetbootin spash screen that keeps counting-down from ten to 0, and then restarts.

  • Help me i can't format my usb? i have already tried with mkdosfs and gparted

    - by Mauri Olivares
    I have a MicroSD card in a USB adapter (which plugs into a USB port on my machine, and acts like a USB flash drive). I was using Unetbootin to make this a bootable USB flash drive with Kubuntu. But I needed to cancel while it was working. So I killed the Unetbootin process from the console. Since then, I can't format the MicroSD or delete the folder that Kubuntu made. I have also tried mkdosfs, with no success. I can't mount the drive anymore either? What can I do, to make this drive usable again? Trying to create a new partition table in GParted, as described in Eliah Kagan's answer, does not work. It fails with the error message "imposible crear tabla de particiones" ("unable to create a partition table").

  • Can realtek 8192cu usb wireless card be used in ubuntu 12.04 with kernel 3.2.0?

    - by waterloo2005
    I do like the post RTL8188CUS Wireless USB Dongle doesn't work unless I disable wireless security . But when I plug my 8192cu usb wireless card, my computer screen is off. At that time I even can not use Alt SysRq k or Alt SysRq + reisub. I compile the latest driver of 8192cu on ubuntu 12.04 with kernel 3.2.0-34. In RealTek site, I download 8192cu drive which is for Linux Kernel 2.6.18~2.6.38 and Kernel 3.0.8. But now in Ubuntu12.04 my kernel is 3.2.0-34. Every time I plug the usb 8192cu wireless card my system halts. Now I try to blacklist both the system's rtl8192cu driver and the new 8192cu driver I compile, but the system still halts when I plug the usb driver. What about you ? Thanks!

  • What does this ssh error mean?

    - by kevin
    This is my last resort. I've been trying to figure out the problem here for hours. Here's the deal: I have copied my private key from machine #1 onto machine #2. Machine #1 is able to connect via ssh to a server with my public key just fine, but machine #2 gives the following output, when trying to connect to the server: $ ssh -vvv -i /home/kevin/.ssh/kev_rsa [email protected] -p 22312 OpenSSH_5.3p1 Debian-3ubuntu6, OpenSSL 0.9.8k 25 Mar 2009 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to 192.168.1.244 [192.168.1.244] port 22312. debug1: Connection established. debug3: Not a RSA1 key file /home/kevin/.ssh/kev_rsa. debug2: key_type_from_name: unknown key type '-----BEGIN' debug3: key_read: missing keytype debug3: key_read: missing whitespace debug3: key_read: missing whitespace debug3: key_read: missing whitespace debug3: key_read: missing whitespace ... Permission denied (publickey). There is obviously more debug output that I have omitted, and I can provide upon request. I am convinced however that it doesn't like my private key file. I also had a suspicion that it has to do with how I copied it from machine #1 to machine #2. I copy/pasted the text from the private key onto a flash drive. This might be the problem, however, when I duplicated this method on another working private key file, and did a diff on the original, to the copy/pasted one, they are identical. I've been struggling with this. If I could just get a little more information on why it doesn't like my key, I could fix it I'm sure. Anyone have any ideas on this? Is there some meta-data somewhere that tells ssh that a file is in fact an RSA key?

  • Results Delphi users who wish to use HID USB in windows

    - by Lex Dean
    Results Delphi users who wish to use HID USB in windows HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB Contain a list if keys containing vender ID and Producer ID numbers that co inside with the USB web sites data base. These numbers and the GUID held within the key gives important information to execute the HID.dll that is otherwise imposable to execute. The Control Panel/System/Hardware/Device manager/USB Serial Bus Controllers/Mass Storage Devices/details simply lists the registry data. The access to the programmer has been documented through the API32.dll with a number of procedures that accesses the registry. But that is not the problem yet it looks like the problem!!!!!!!!! The key is info about the registry and how to use it. These keys are viewed in RegEdit.exe it’s self. Some parts of the registry like the USB have been given a windows security system type of protection with a Aurthz.dll to give the USB read and right protection. Even the api32.dll. Now only Microsoft give out these details and we all know Microsoft hate Delphi. Now C users have enjoyed this access for over 10 years now. Now some will make out that you should never give out such information because some idiot may make a stupid virus (true), but the argument is also do Delphi users need to be denied USB access for another ten years!!!!!!!!!!!!. What I do not have is the skill in is assembly code. I’m seeking for some one that can trace how regedit.exe gets its access through Aurthz.dll to access the USB data. So I’m asking all who reads this:- to partition any friend they have that has this skill to get the Aurthz.dll info needed. I find communicating with USB.org they reply when they have a positive email reply but do not bother should their email be a slightly negative policy. For all simple reasoning, all that USB had to do was to have a secure key as they have done, and to update the same data into a unsecured key every time the data is changed for USB developer to access. And not bother developers access to Aurthz.dll. Authz.dll with these functions for USB:- AuthzFreeResourceManager AuthzFreeContext AuthzAccessCheck(Flags: DWORD; AuthzClientContext: AUTHZ_CLIENT_CONTEXT_HANDLE; pRequest: PAUTHZ_ACCESS_REQUEST; AuditInfo: AUTHZ_AUDIT_INFO_HANDLE; pSecurityDescriptor: PSECURITY_DESCRIPTOR; OptionalSecurityDescriptorArray: PSECURITY_DESCRIPTOR; OptionalSecurityDescriptorCount: DWORD; //OPTIONAL, Var pReply: AUTHZ_ACCESS_REPLY; pAuthzHandle: PAUTHZ_ACCESS_CHECK_RESULTS_HANDLE): BOOl; AuthzInitializeContextFromSid(Flags: DWORD; UserSid: PSID; AuthzResourceManager: AUTHZ_RESOURCE_MANAGER_HANDLE; pExpirationTime: int64; Identifier: LUID; DynamicGroupArgs: PVOID; pAuthzClientContext: PAUTHZ_CLIENT_CONTEXT_HANDLE): BOOL; AuthzInitializeResourceManager(flags: DWORD; pfnAccessCheck: PFN_AUTHZ_DYNAMIC_ACCESS_CHECK; pfnComputeDynamicGroups: PFN_AUTHZ_COMPUTE_DYNAMIC_GROUPS; pfnFreeDynamicGroups: PFN_AUTHZ_FREE_DYNAMIC_GROUPS; ResourceManagerName: PWideChar; pAuthzResourceManager: PAUTHZ_RESOURCE_MANAGER_HANDLE): BOOL; further in Authz.h on kolers.com J Lex Dean.

  • How to safely remove a USB drive on Windows CE 5.0?

    - by Radu C
    Until today, I assumed that Windows CE was writing everything to disk and I wouldn't end up with a broken FAT16 when I removed the USB stick. Today, I was proven wrong. I use a USB stick to test things on a WinCE 5.0 device. I don't write anything from the app or WinCE to the stick. I just execute my app, and my app reads its settings and pictures from the stick. Today, just this order of operations broke my stick filesystem (and I have to fix it). Is there a way to tell WinCE 5.0 to unmount the stick before I remove it? It sees it as a "Hard Drive", and the tap-and-hold menu has nothing along the lines of "safely remove drive". I'm happy with both code to do this operation and some trick that I didn't find in Windows CE yet. Thank you.
