Boot to a live linux or bartsPE disk and see if the usb works.

Why did it take me over a year to phone in a problem to ATT?

It may be in Fat32 or Fat16 formats, especially if the other computers are XP machines which still support that format. If you copy everything that is on it and reformat it to NTFS then it should work on both systems.

You have to be a little bit crazy to keep you from going insane.
If all else fails, read instructions.

Pretty sure Windows 7 can read any XP format.

It has nothing to do with the format.

uninstall your usb controllers from device manager then reboot.
However if your flash drives work on other win 7 machines, and you are certain that the usb ports are working, then you obviously have a software issue, create a new partition, install win 7 on it and see if your ports work with your flash devices,
if they do you would be advised to save all your files and factory restore your machine, then put back your files..

Question (that might help),,,, Could you have a BIOS setting that would allow/disallow the use of USB Hard drives, since flash drives are recognized as drive similar, they might be effected. A BIOS setting change or BIOS update might solve the issue....

no way in hell your going to reinstall windows, it takes too long..;-) how long have spent pulling your hair out over this issue?, installing win7 on a separate partition will take 30 mins max..and may point to the issue..you can always delete it afterward..
a factory restore takes 20 mins max, however i understand installing all the other software is a pain, but what do you want a fully operating system or constant frustration?
if your usb ports work with everything else, it has to be a setting or damaged file, afraid ive never found a setting that can switch off flash devices/external drives, but it may be a registry settin, have you played with any registry managers?

# Click Start Menu > go to run command and type "regedit" without quotes. Registry Editor will open.
# Expand the HKEY_LOCAL_MACHINE folder then SYSTEM >CURRENT CONTROLL SET > SERVICES >USBstor, located at the left pane.
# Find "Start" in the right pane with the blue icon.
# Double click "Start". A box titled "Edit DWORD value" will open.
# Write down "3" in the "Value Data" Field.
# Click OK and then close the Registry Editor.
if it was a # 4 in the field your machine was set to ignore flash drives
