Are my USB ports working properly?

[venom0706]

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.

have you installed chipset drivers and usb drivers if available?

Yes, of course. All drivers are up-to date. No yellow exclamation marks in Device Manager either.

if i understood correctly it's only 1 flash drive having problems? Does it work perfectly on another pc?
