Ya Im sry didnt see the sp3 at the end..You did it right, go into
safe mode, remove the usb entries from device manager, reboot, and
usb should realign its self.. The drivers for usb2.0 are included in sp2.
Something on that dvd really whacked something out..Not sure I
would trust that thing anymore.
You may try installing mobo drivers again, couldnt hurt.
