PNY, find a 4 G USB flash drive that is broken.

Haha, my problem is the same as yours. I have already dealt with it! Find PNY official website and call 800 for a solution:

/craftness . ASP？ Id=2 Download that Ufix, and then follow the instructions inside to fix it.

At first, a USB plug couldn't be repaired, so I changed it. In short, if you can't, just try a few more times!
