I am running Windows Media Center. Any time I try to connect a USB Mass Storage Device Windows says it cannot find the drivers and asks me for a disk. I've looked and the Windows driver usbstor.sys file is where it is supposed to be. I'm a newbie. What can I do?

It is possible that your USB drive requires specific drivers. I personally have had trouble with USB drives in the past that require specific drivers. Try looking on the manufacturer's website incase there is a support download.
