It could be the USB controller hardware and whatever firmware it has. I have had serious problems using an Epson scanner with a Via chipset + USB controller and zero problems using the same scanner on an Intel chipset + USB controller. Both are UHCI. Things get worse using uhci.o instead of usb-uhci.o and things break using alt-uhci.o. I have other problems with the Via set, as well and the messages are very similar if not identical. It is so bad that I have to shut down the system to get rid of the problems. I have to do that every time I use a USB device. Just a thought... =-= jd
