I've tried several USB ports on several different computers with no luck.
I've resoldered contacts and traces on USB drives before but from what I
can see nothing is visibly broken. As noted in my other email since the
drive responds and IDs itself I'm guessing the flash chip BGA array is
broken, which I have no ability to do anything with. The drive is still
sold so if I can find someone that can do BGA work it would
theoretically be possible to move the flash chip to a donor drive, but I
have no idea where to look for that.
