Have you tried putting it into a different usb port?

What OS are you running? There have been issues with Windows 7 that makes it necessary to uninstall all the USB devices (in the hardware manager tool) and then reboot. The OS automatically reinstalls the required drivers. After rebooting, reattach the USB drive and you should get your connectivity back. I've been having this problem on 2 Windows 7 systems for the past 2 years... The USB ports seem to work for Most everything else, but not for USB flash drives. So far, I have not lost any data.

FWIW, a number of my colleagues have had the same problem, though it has also has been an issue with some usb hardware interfaces to our device diagnostic tools that integrate with the JTAG interfaces on our consumer gear.
