Are my USB ports working properly?

After a re-install of Win 7, I've noticed that one of my flash drives is acting weird when I put it on either a USB 2.0/3.0 port. The system starts reading it, but it takes around 2 minutes for it to complete. This doesn't happen with my other flash drives. Any idea what the problem might be? How can I check whether all my ports are working properly? Thank you.
