So it's possible that your EHCI controller isn't working right. > Plus I have a digital camera, a digital video camera (so far not tried > under linux), a memory stick and usb-hdd that I also use... hence the > hub.

If the USB HID code had a problem, it would show up the same no matter which host controller you use. Are the errors you see still the same as this?
