Try both front and back usb ports. Also try connecting directly to the pc and not via usb hub. What kind of device are we talking about here?

Check this: Go to administrative tools (in Windows ) -> Computer managment -> Storage -> Disc managment -> right click on flash drive and chose Change drive let... -> click change -> chose another letter an click OK

I'm using Windows Vista
