Before you install the driver, you are going to have to delete all of the old USB drivers. You can do this by right-clicking on "My Computer" (if you don't have a mouse, use tab and arrow keys to select "My Computer" and press the menu key.) and select properties.

Once in properties, select the "Device Manager" tab and scroll down to the bottom.

Expand the "Universal Serial Bus controllers" and delete all of the drivers.

Now you can close out the properties menu and return to the desktop.

All that is left is to run "nusb36e". Just run the driver, accept the Licence Agreement, and install it.

After you are done, simply restart the computer and when it reboots you should have access to USB flash drives.

Something to keep in mind: I can't guarantee that every drive will work, so if your drive is still not recognized, try a different flash drive. I'd also suggest using USB 2.0 drives.
