I have a computer and it does not matter what usb port I put the usb flash drive in, it will not recognize it.  It shows up as unknown device in device manager.  I have tried all 6 ports, front and back, I have tried different usb drives, even a new one and it will not see the device.  I have removed all usb devices from device manager, I have removed them and unplugged the computer for 30 minutes and still nothing. I get a message usb device has malfunctioned.  The sticks work fine in other computers and a usb mouse and printer work on the computer.  I have moved them around and they still work.  Finally i did a system restore point and still nothing.  Thank you for your time.  This is happening on a windows xp computer with sp3

Have a look in DISK MANAGER and make sure it is properly formated.

-Right-Click then Manage on MY COMPUTER then Disk Manager....

-Have you used it before?

hey try these..
 Check for permissions in usbstore.inf and usbstore.pnf available in %windows%\inf and usbstore.sys in %system32%\drivers folder...

Then try open usbstore.inf and check for start is set to 3 (search for start)

The files referenced above is called usbstor.inf/pnf and usbstor.sys.....   :)

I would actually navigate to that file, c:\windows\INF\usbstor.inf, and right click it>Select Install.....

Also, is the Removable Storage Service running?

Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.

Try this :
Remove all USB drivers reboot and
 Delete the "UpperFilters" and "LowerFilters" registry values from:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}

restart and try.

From these two solutions I was able to get the flash drive to work once but as soon as we moved it to another port the issue would come back.
