Problem with 2 USB flash drive in Windows XP sp3.

I have a USB 2 pci card - USB 2 card, with the hub 7 ports (powered) USB. Sometimes, everything works fine. Most of the time I can't access flash USB dirve. Printer, scanner, camera, photo, mouse, all connected work very well. Plug the flash drive and errors occur. The flash player works fine in laptop (Win xp sp3). Difference between the two machines, the laptop has only 2 USB ports. Have tried to uninstall the USB controllers and re-setup. Flash drive works fine in the desktop integrated USB 1.1. Have checked with Kingston USB drive flash technical support without success.

When dirve flash does not, Device Manager displays the flash player at the top of the page section of controllers USB bus, as well as generic USB (USB 2?) hub. When the flash works do not drive, hub Generic USB appears in the second USB bus controllers.
Someone help? Please, I beg you.

Hello

Tried your suggestions, without success.

Have now connected powered hub USB 2 on my edge USB 1.1, with all devices USB works fine.

Probability of problems seems to be my pci - USB 2 card.

Being disabled, it is very convenient for me to have the hub USB 2 powered on my work surface to facilitate the connection of my devices.

Thanks for your help anyway.

  • How to replace a bad IDE disk with a USB Flash drive system - and have all the functionality of XP Pro SP3

    How to replace a bad IDE disk with a USB Flash drive system - and have all the functionality of XP Pro SP3
    Given a PC without hard disk...
    How can you use a flash drive instead?
    So, indeed, the USB key works as an SSD...
    I saw online options that gives partial functionality of the system... and an option that is more than $100 (more than the system's worth)...
    None of these options are acceptable in the circumstances.
    It is an effort to create a machine for a particular use, built from a recycled pc for which hard drive was removed and destroyed by the original owner...
    The criterion is that it must work just like it was a mechanical drive running xp pro sp3 with all updates, etc...
    Thanks for any help.

    You can not install XP on a Flash as his unsupported drive. Your only two options are a traditional hard drive or Solid State Drive (SSD).

  • How to recover from the failure of a with ESXi USB flash drive?

    I have ESXi 5.5 running on a 16 GB USB flash drive.  The system itself has a RAID card and drives mirrored where all virtual machines are stored, so it seems to me that a critical point of weakness is the drive itself.  If die ESXi itself running flash player, is there a procedure to recover the virtual machines on the disks?  Or should I keep a backup of my drive as well?

    1. How to restore the operating system assuming that the flash drive fails? If I reinstalled ESXi on a new drive of the same thumb, would see the VMware VMs existing on the hard drives of the server? Or is the process of discovery of the relatively painless existing virtual machines?

    If your flash drive goes down, will not be a problem that you have your virtual machines without danger on the separate data store in the locally attached storage drives. all you got to do is to reinstall ESXi host, he will be happy to see the existing VMFS data store and browse this data store where are stored the re-save you and virtual machines in the inventory.

    See also changes following KB to make the backup of your ESXi as operating system configuration and when you change the configuration at the time of the failure of ESXi, you don't have to worry about re-configuarting it

    VMware KB: Backup and restore configuration using the vSphere command-line Interface and vSphere PowerCLI ESXi

    1. How can I maintain redundancy for my USB failure? Can I have two drives connected and automatically backup flash / mirror the first hard drive to the second?

    This is not possible (I never tried myself) If you use an external flash drive, but let's say that you have any material to the specific provider giving this feature as

    DELL IDSDM http://www.dell.com/downloads/global/products/pedge/en/poweredge-idsdm-whitepaper-en.pdf

    or another supplier giving a similar feature, then it is quite possible to mirror. Otherwise, the best option is take config. backup using KB, I mentioned in the first answer.

  • Problem opening of my flash drive in windows 7

    Hello everyone! I plugged a dive flash to my computer and then my antivirus (Bitdefender) says it has virus (horse of Trojan and malware) and told me that they should be deleted and after the scan is complete, whenever I try to open my drive (USB) flash, I see a shortcut (size of 1 KB) and when I try to open it shows this message (there was a problem starting pvd3z8... (a lot of weird things)-the specified module could not be found. :(:(veuillez s'il vous plaît aider.)

    Hello!

    I suggest you to format the flash drive using HP Format reader tool.

    Most likely your USB has on him a virus that starts with AutoRun, so you're very very likely to infect your computer, if you perform the following steps to manually remove the virus from the key.

    I had a case on a PC with a virus VBS (Visual Basic Script) who himself reinstalled in the computer every time a letter assigned to the USB and every time you have double-clicked on USB key in 'computer '.

    To manually remove the virus from the stick:

    1. go in disk management and assign a letter on the pendrive

    Start--> Diskmgmt.msc; in management of drives, right click on the USB drive and select 'Change drive letter and paths', click 'Add', assign the following drive letter... Ok

    2. open administrator command prompt

    Start-> Accessories-> right-click "Command Prompt" and select "Run as Administrator"

    3. navigate to the USB, identify the strange hidden files and delete them

    CD d:\ (if d: is the letter of the USB drive)

    Dir /ah-> for show hidden files

    attrib - a-s-h - r-> to view the files

    del autorun.inf

    del file1

    del File2

    where File1, File2 is the names of suspicious files which are hidden files before. You can use the TAB key after led to select files easier.

    4 remove the USB

  • Satellite Z930 - suspend the problem with connected USB hard drive

    Hello

    Owner of a newly acquired Satellite Z930-15 X, I have a few questions/problems:

    1) suspends the work of RAM and good hibernation when there is no external hard drive connected. If there is one is connected, the laptop immediately returns back to suspend state. Is there a solution for this?

    (2) is there a way to selectively disable Bluetooth? Currently, only toggle airplane mode is available (with Fn + F8 or Windows 8 charm bar). This activates / deactivates the Wi - Fi or Bluetooth I think.

    (3) the portable computer is wobbly on reception. I put a bit of thin paper at the corner of a bottom (bottom left) so that it can be stabilized. Apparently, the problem is also mentioned in another thread. Is there a suggestion to fhix this problem?

    Thank you.

    1 / what HARD drive is connected to your laptop? When I use the external 2.5 HARD drive with my Satellite U940 I n t have problem.

    2 / I ve tested it on my machine and I noticed the same thing. When WIFI is disabled software BT is off too. I didn t find a way how to separately control adapter WLAN and BT.

    3 / I think that this issue needs to be clarified with Toshiba service. They must check and perhaps exchange rubbers inside.

  • "Unknown device" USB Barcode scanner, problem with the USB controller driver?

    Hello

    I need assistance with our Barcode Scanners that doesn't work on our newly purchased computers at HP with Windows7 Pro x 64 operating systems.

    The brand and model of the bar code scanner is:

    Datalogic Heron D130 USB.

    When you connect the scanner to a USB port, Windows will try to install this as a HID, but it takes an unusually long time, about 7-8 seconds, to boot the device and install the drivers and appears as an unknown device in windows "devices and printers" and the hand scanner does not work.

    Sometimes when you move the USB back can I sometimes the scanner at hand to be recognized as an HID device or a Datalogic barcode scanner,

    It works fine until you restart the computer.

    After restart the computer cannot detect the scanner Barcode correctly without re - appears as unknown device.

    I suspect that there is a compatibility problem between barcode scanner and card USB controller on the computers.

    I tried to update all the drivers available on the website www.hp.com and same www.Intel.com (chipset drivers) but nothing has helped to solve this problem

    Tried newly bought barcode scanners and "used" barcode scanners earlier who works on other computers, but the problem remains.

    I found a workaround by connection of bar codes in a USB hub, and then plug the USB hub to the computer.  And leave the USB - hub to take care of the communication with the Barcode Scanner.

    in this case, it takes about 2 seconds for the code scanner barcode to mount correctly in windows under the heading "devices and printers" and then works perfectly, even after a reboot.

    I googled after a response after my problem, but it seems I'm the only one who experience this issue. ?!

    Bought more than 40 computers that I have this problem.

    These were bought at different times with two different for suppliers

    Computer model are the following

    HP ProDesk 1 400 P/N5S21EA

    Specifikations:

    http://WWW8.HP.com/emea_africa/en/products/desktops/product-detail.html?OID=6614160#! tab = specifications

    Does anyone have an idea what could be wrong and how to fix it?

    Thanks in advance

    Hello

    The problem is not power - related.

    We use passive USB hubs that solves the problemon these computers.

    (it also works with the docks, or if you EliteDisplay E241 HP as we thers a usb hub 2 ports inbulit in monitor that works.)

    The problem lies in the incompatibility between the Intel USB controller and the hand scanner, can be connected to USB 3.0

    When you let another usb-controller support in handshakeing (such as a usb hub), it works.

    Datalogic or Intel would like to acknowledge this error.

    Because none of the big companies want to acknowledge the problem or repair, personally chose to switch to an AMD platform / CPU instead of the Intel and now it works fine!

    We get more performance for your money when AMD is usually less expensive to purchase.

    And because of the poor of Datalogic press where they don't even answer e-mail (their only channel for support)

    I chose to stop using their products. I'm going to use another provider / brand of barcodescanners.

  • Problem with actionscript in Flash CS3 IDE window

    The actionscript window opens not upward for all frames on the timeline. When I press "F9" or try to access it via the context menu of the action of the window tab appears at the top in reduced form. No matter how many times I click above or the button larger, that the window does not open. I tried to reinstall Flash CS3, but it did not help.

    Found a solution for this atlast! Remove the Users/AppData folder for flash CS3 and things will be back to normal. Somewhere, it seems the screws of the IDE Flash and save settings for local users. These parameters of compensation restored my window of action!
