No. > Does it start working when you load usbmouse? Does not. This is what did the trick. Removed all these modules: mousedev 3736 0 (unused) hid 17892 0 (unused) usbmouse 1784 0 (unused) input 3296 0 [mousedev hid usbmouse] usb-ohci 17672 0 (unused) so that the only one that remained was this: usbcore 54592 1 which refused to be rmmod:ed. I subsequently modprobe:ed usb-ohci, and all this bunch came back: mousedev 3736 0 (unused) hid 17892 0 (unused) usbmouse 1784 0 (unused) input 3296 0 [mousedev hid usbmouse] usb-ohci 17672 0 (unused) usbcore 54592 1 [hid usbmouse usb-ohci] and my usb-mouse became usable again ;-) So, there seems to be some relationship between usb-ohci and the rest, but I have to admit: the logic around this stuff is not obvious to me. Trial and terror seems to be the way to go ;-) Don't dispair! You'll get it working, eventually ;-) It also seems to me there's different behaviour, depending on the kernel version. Cheers, Cristian
