I have a Mythos Apollo laptop, basically a rebadged Clevo laptop (D47EV) that I've had this issue with but I just can't seem to fix. If I plug in any device into the USB ports Windows (XP SP3) comes up with the dialog of "USB Hardware Not Recognized" no matter what the device is if it's a mouse or a USB stick. There seems to be voltage coming off the ports as I can plug in a USB lamp and it lights up. I've tried going into safe mode and removing all of the USB devices along with the controller and hubs from the device manager and then rebooting into normal mode. It finds the AVermedia TV USB 2.0 that's built in to the laptop along with the webcam along with the controller but it still will not recognize any devices hooked into the USB ports. Any ideas?
