My Usb Flash Drive Won't Connect To Mac

I'm New

Guys 'n' Gals

A month or so ago I tried to plug my falsh drive(bought in popvoucher )into my MAC to send some photos. The USB said it was being charged but the MAC seems to have no linking that it's connected. I can't force it to pick it up when it can't see anything there at all. I've not been able to connect it to the MAC since

Can anyone suggest what might (not) be happening?

Try manually holding up the end up the flash drive, wiggling it around, etc. You might have to do what I have to do, and manually do this until the file transfers are done.
