Sven Schuster wrote about this problem about a week ago and suggested to turn off USB support and something else, but he wasn't able to get the scroll function to work again. I have the same problem (but I've only turned off USB support and rebooted once, so far so good but no scrolling). I just subscribed to this list, so I might have missed a follow up on the web-archive, but, Sven, have you had any progress in trying to find a working elegant solution? Or anybody else? Sjors
