Re: USB Flash Drive Not Recognized
the OP says 3 different computers have been used, so yes. Try putting the usb drive in the computer and restarting the computer. if that doesn't do anything and it still doesn't show up in disk management then I'd say your drive is toast.
The only thing i can think of that would be happening if nothing works is that it recognizes that there's a device connected, but as you mentioned the connection between the flash drive and the usb connection might be broken, which is why when you point to it with a driver nothing is recognized.
Have you tried any of the options in the device manager when you bring up properties?
