Mine lets you choose between > USB 1 and USB 2 speeds for the EHCI controller. The ehci can only do high-speed and the uhci companion only full and low speed. The BIOS is broken if it speaks about full (or low) speed on EHCI. > I have: ehci0: Yes - but you device is not attached to your ehci controller. -- B.Walter BWCT http://www.bwct.de bernd@bwct.de info@bwct.de
