  • How can I get my HID device working in VirtualBox?

    - by Andy E
    I'm running the latest official Ubuntu build of VirtualBox (4.1.12), with Windows 8 running as the guest OS. I have a Windows app that works with a card reading HID device, but it's not detected by the guest OS at all. I've installed the USB extensions, guest additions and set my udev rules accordingly (my own linux app is able to access the device), but no joy. Does anyone know how to get this working?

  • Is that possible to natively boot Ubuntu Touch on a PC, especially on a Surface Pro?

    - by Jules P.
    I know the question has already been asked, but the link for the instructions in the answer is outdated and the proof of concept video doesn't match with what I'm looking for. I've got a Surface Pro (1st model), I've already ran Ubuntu and Android on it several times with UnetBootin, so the question is : Is there a way to natively run Ubuntu Touch (By natively I mean by directly booting it, even on a USB key, but no emulation, no virtualization) on such a device ?

  • Why am I getting such slow file transfer performance?

    - by kingdango
    Copying 4GB from a USB flash drive to my Linux partition. The flash drive is NTFS formatted (I believe, it's Windows formatted). The transfer is incredibly slow and blocks the computer frequently causing lag and hanging applications. My transfer rate is 1.2 MB/sec and that is the max it has hit when I let the File Operations window have focus. Why is this so slow under Ubuntu and significantly faster in Win 7?

  • How to run sunspots?

    - by user111317
    I am trying to use SUN Spots with Ubuntu, but for some reason the SUN Spot Manager app is not seeing connected spot on USB port. Possibility that cdc_acm driver is not installed has been mentioned elsewhere, but I am complete beginner when it comes to Ubuntu, so I don't know where to find it or how to install it. Any input on this matter would be more than welcome. Addition: ls /dev/tty* returned the list that contains /dev/ttyACM0, but SUN spot is still not recognizing it.

  • How does a hard drive compare to Flash memory working as a hard drive in terms of speed?

    - by Jian Lin
    Some experiment I did with hard drive read/write speed was 10MB/s write and 40MB/s read, and with a USB Flash drive, it can be 5MB/s write and 10MB/s read. Also, if I put a virtual hard drive .vhd file in a hard drive or in a USB Flash drive and try a Virtual Machine using it, the one using the hard drive is quite fast, while the one using the USB Flash drive is close to not usable. So I wonder some early netbooks use 4GB or 8GB flash memory as the hard drive, and even the Apple Mac Air has an option of using flash memory instead of a hard drive. But in those situation, will the speed be slower than using a hard drive, like in the case of a USB Flash drive?

  • Using "offline files sync" to sync with a local resource [closed]

    - by Kije
    Possible Duplicate: Which is the best application to Sync two folders? I have been trying get my machine (XP-Pro SP3) to sync files to a local USB drive in the same way as I can with mapped network drives. I particularly want to the sync to happen automatically when the USB is connected - in the same way that Off-line files will sync when the network drive comes on line. I can get a folder on the USB mounted as a network drive, but cannot get XP to offer the off-line files functionality. I have tried MS's SyncToy - it works as advertised, and will do scheduled and ad-hoc sync's, but does not seem to offer automatic syncs. I suspect I could do this by plugging my USB into another machine on my network - but that seems heavy handed. All insight appreciated - If you know this cannot be done please say so.

  • Is there any USB2.0 data transfer chunk size limit?

    - by goldenmean
    With one read() or write() at a time, can we increase the bulk data size over USB interface? For example, I want to transfer chunk of 1024 (1K) bytes data and if the device has limitations of only 64bytes, is there any way I can increase the packet size for read() and write() system call over USB? Is there any limitation on size of data transfer over USB in a host-device environment?

    I used truecrypted V.6.3a to partially encrypted (5gb) on my 16gb usb flashdrive on my XP netbook and eveything was fine. However, I don't see the ecrypted partial (5gb) when stick the usb into windows 7-32 bits (desktop). Tried to re-encrypted the usb on windows 7 (desktop) but results are the same. No problem seeing it on XP but windows 7. Thanks

  • Standalone tool to synchronize two folders in windows?

    - by Jim
    I keep data on a USB drive, but I also keep a copy of all of that data on a hard disk. I like using the hard disk because it's faster and gives me a backup. What standalone tools would work to keep the files on the disk and USB drive in sync? I'd like a single command line executable or standalone GUI app that can do the job--something I could run off of the USB drive. So, things like the MS Sync Tool wouldn't work.

  • What is the solution to enable Dymo Turbo 400 Label Printer to work on Win 7 / 64-bit?

    - by mdpc
    It's Christmas time and time for printing labels for all those Christmas cards. I've upgraded to Windows 7 64-bit from XP. I've been unsuccessfully attempting to get the connected Dymo 400 Turbo label USB printer to work again. The latest manufacturer drivers have been successfully loaded and installed. The drivers are supposed to work on Windows 7/64-bit. The Win 7 system(s) in question are patched and up-to-date on that score. The Windows Update site responds with a driver when the USB cable is connected to this printer. The printer queue seems to be established correctly. What happens is that I submit a job to the printer (either using the DYMO s/w or not), it delays for a period of time, and then I get the message 'printing error'. Can't seem to locate the appropriate error in the new and improved event log. Several combinations of rebooting, re-installation and power cycling components fail to make the printer work. Sometimes during some type of reset it spits out the last thing to be submitted, but that seems intermittent. I have tried different USB cables and different USB (2.X) ports as well. I have run the Windows 7 troubleshooter it tries to fix the problem but alas it doesn't. Interestingly, trying the USB printer (and its associated manufacturer drivers and s/w) on another Windows 7 64-bit system has the identical failures noticed on the original system. I did not find anything on the manufacturers' site concerning this problem. The printer has no hardware problems or issues.

  • make a folder/partition on one computer appear as a mass storage device to another?

    - by user137560
    Is there anyway to make a folder or a partition on a computer (Linux or Windows) act like a mass storage device to other computers or devices when connected with a Male-Male USB cable? For example, I have a Windows 7 computer with 2 partitions, C and D. I would then connect that computer to another computer or a Smart TV using a Male-Male USB cable, and the other computer or device recognizes a folder/partition on current computer as a mass storage device. Is this possible? If not, is there any USB switch that can connect an external hard drive or flash drive to both a computer and TV without the need to manually switch them? (I know about some USB switches, but they only support automatic switching with some certain types of printers, not with mass storage)

  • Multi mouse, keyboard and monitors

    - by Click Ok
    I've got a USB hub with 4 ports, and I've plugged 2 usb keyboards and 2 usb mouses. They work very fine. I've setup'ed 2 monitors too, so I was thinking about the possibility of the mouse and keyboards works independent one of another. I want two mouse pointers (I think each with different colors) and 2 keyboard cursors. I think it a nice idea, but I don't know if this is possible... :( PS: My OS is Windows7

  • what happens when you plug in a new USB device?

    - by Will
    I have an embedded device with a USB connection. When the user plugs the device into their PC (Windows, OSX), how does the operating system discover what drivers to install? How do I get my drivers to be selected? Can they reside on some central server (run by the OS vendor)?

  • External USB Drive

    - by ErocM
    I have a server that I hooked up an external USB drive. It was formatted in windows and has files on it already. I'm new to Ubuntu so please be patient... I have two questions: Will Ubuntu see the drive since it was formatted in windows? How do I mount this drive or rather, how do I know it's seen by Ubuntu? Thanks! I did fdisk -l and this is what I have but I don't see it.

  • Internet Timeouts with TP-Link TL-WN821N v2 wireless usb stick

    - by user1622959
    A short time after accessing the internet, the browser/download times out. Before the timeout, the internet works OK briefly; afterwards, the wireless is still connected with a strong signal, but every internet access results in a timeout. When I leave the PC for a while, the internet is back just to timeout again as soon as I start using it. The same happens when I reconnect to the router. Also, when I surf the internet, it takes a couple of minutes until the timeout, but when I download something, it times out in a matter of seconds. The wireless adapter works just fine in Windows and internet via ethernet cable works just fine in Ubuntu. Does anyone have the same problem or knows a solution. I use Ubuntu 12.10 x64. The problem occurs since I installed ubuntu (which was a few days ago). Here some stuff that might be usefull: serus@serus-Ubuntu-PC:~$ lsusb Bus 002 Device 002: ID 0cf3:1002 Atheros Communications, Inc.

  • How do install Ubuntu from a USB stick?

    - by Sophia
    When I go to the boot menu on my computer and select USB stick, the screen goes black and there comes a flickering underline. Like I could write something. But I can't. Whatever I push, nothing happens. Except the PrintScrn/SysRq button. When I push it, mu computer beeps. I get no choose menu. Nothing. I found out the usb stick is in msdos format. So what format should I use and how can I format it? I am not a computer geek who knows everything. I'm just a beginner. And only 16 years old. I've got a new problem. The screen isn't black anymore. Now there comes an error message: SYSLINUX 4.04 CHS 20110518 Copyright (C) 1994-2011 H.Peter Anvin et al ERROR:No configurationfile found No DEFAULT or UI configuration directive found! boot: And when I write something: boot:example Could not find kernel image:example boot: Why does this fail all the time? ps. I'm using Ubuntu Oneiric 11.10.
