Bought a friend a WUSB54GS for Christmas. I just stopped by earlier this evening to set it up. Ran the install disk, connected the WUSB54GS and seemed to be doing well. Decided to reboot the PC and encountered problems. It posts without error, but just about the time it should be loading Windows all HDD activity stops and there you sit... staring at a black screen. I've tried rebooting with and without the USB adapter connected, always with the same result. i've tried booting to safemode as well, and get to the point where it seems to be loading MUP.SYS (or MVP.sys perhaps) where it seems to hang indefinitly. Even popped the Windows XP Pro Setup disk in and tried to repair windows... after it finished copying all of the setup files to the hdd, it rebooted and once again just sat there staring at a blank screen. The PC in question is running XP Pro SP1, by the way. Please help me to resolve this problem!
