I hate microsofts troubleshooting, it makes everyone run through loops trying to fix there problem, further more, try to install the software bundled with your usb product before you connect, it will eliminate some driver problems, or when the little drive dialog box comes up, insert the cd, or dl the drives from manufacture's site, and select No, dont allow Microsoft to look for drivers, and then next select look in a specific place, and then guide it to where thoes drivers are that you dl, or point it to the cdrom drive where you put installation cd in.
