USB Flash Drive Tester
I am looking for a tester to use to test USB Flash Drives. I found a cool USB port tester on instructables, but I need something that would test the hardware functionality of a USB Flash Drive not the USB port. I am not sure if I am saying this correctly, but reading about the functionality of USB Flash Drives, it appears to be a fuse on the circuit board. I don't know if all drives have one. Many of the videos I watched on YouTube require taking apart the drive and jumping the fuse to see if this is the problem. I thought if there was a way to test to see if the circuit (I am not sure if I am describing this correctly.) was completing then it would not initially require someone to take it apart.
Looking into this a little further, I see there are four leads on a USB. It looks like from what I read that lead 1 [+5 VDC] and lead 4 [ground]. Are these the two leads which should show a completed circuit via a tester? You probably have already figured out by now that I have no knowledge of electronics.
Thanks for your help.
