No.

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
