Finally fixed the mouse pad problem Used Tom Horsley fix by adding the following line to /etc/modprobe.d/options options usbhid.quirks=0x046d:0xc71f:0x00080000 rmmod usbhid modprobe usbhid and all came right ... :-) As usual with linux I learnt a lot - this time about usb hid, quirks, modprobe configuration, udevinfo, /sys/module/.. and so on.
