If this problem is occuring on your PC, try a different power supply. The guy who's PC was crashing randomly is more than likely a PSU problem. Adding the extra USB device could be the straw that broke the camels back, drawing that little bit too much power and crashing everything. If the whole PC shutsdown, its probably that or overheating. For laptop users, try faffing about in the BIOS for something related to USB. Turn it off, boot, turn it on, boot and try again. You'll find the option in Integrated Peripherals, Connectivity or similar. (Hammer F2 or delete during start up; straight after you switch on your PC). If a USB device isn't recognised in your PC, try it in another to see if the same problem continues. If it does, the device is to blame not your computer. Newer USB devices ONLY work with USB 2.0 and not 1.0 or 1.1 which can cause Windows to say that its not recognised. If its a cheap USB device then it'll not be backwards compatible with 1.0 or 1.1. My aging Sony Vaio loses the whole side connectivity if its on battery power randomly. That includes the USB ports and the sound card. It acts as if they aren't there, which sounds like a power issue. Sticking the power cable in and restarting fixes the problem. Just to let you know, Microsoft unfortunately don't care about your problems as you have already bought their product. The Vista bug will be worked out by the motherboard manufacturer not by Microsoft. Check their site for additional updated drivers. Hope this helps someone
