    Do you have mapped network drives immediately following your last logical device (eg E:, F:, or G:)?  If so, the device is probably mounting to the same point as one of those drives and thus becoming "invisible".

    To solve:
      1) Hit start
      2) Run
      3) "compmgmt.msc"
      4) Go to "Disk Management"
      5) Find the USB drive in the list
      6) Right click and choose "Change Drive Letter and Paths..."
      7) Assign a letter not used by any network drive

    i could not find it in the list. And now im getting an error USB device not recognized. It has been like this. Sometimes It recognizes it and says the name correctly ( I have tried at least 3 different removable storage devices, like pin drives, usb hard drives, etc). But even when it says its been installed correctly it never shows up in my computer. Its been like this for months.

    In Device Manager, roll down to USB entries and delete all. Restart system if required and let windows redetests and reinstall drivers for them. Try that see if it helps.

    Are you using xp with service pack 2?

    if the above does not help, try this :

    unplug pc from power for 30 minutes
    then test
    choose no to NOT overwrite existing files.
     copy the USBSTOR.SYS from a working PC to the bad one.
    normally located at c:\windows\system32\drivers
    copy C:\Windows\Inf from aworking pc to the bad one.
