USB Flash drive no longer recognized in any computer

My CPA's flash drive (8 Gb Sandisk Cruzer) was working fine until a couple of days ago.  After trying to see it in 3 computers I opened the case to see if there were any broken solders or burned chips - negative on both.  I uninstalled all the root hubs and rebooted with the flash drive inserted.  Windows re-installed all the hubs but still doesn't see the drive.  Any ideas?
Thanks

Flash drives can go bad.  Go to your backups.  Don't have them?  You can try data recovery but I don't think the odds will be very good to recover (though I've never tried).

And you can try some of the solutions here:

Broken solders are the most common cause. The breaks can be hairline or smaller - did you examine with a strong magnifying glass?

I did look at it with a magnification visor.  Was trying to avoid the time and expense of data recovery service but looks like it's time to bite the bullet.  Thanks for the ideas.

Sorry for the delay.  Just found all the notifications in my junk mail.  Data was recovered by Sandisk recommended LC Technology.
