Having vaguely similar issues with other drivers brought up this page on blacklisting that also happens to mention drivers that are known to interfere with usbhid. Here is a small snipped from among the other fixes posted there:
# in /etc/modprobe.d/usbhid-fix-detect.conf
# do not use "Boot Protocol" drivers, we prefer usbhid
# and they cause problems when loaded together with usbhid (#37726, #40861)
blacklist usbkbd
blacklist usbmouse
(It might be well to have a method of logging in remotely or using something like a spare Bluetooth or PS2 keyboard in case of keyboard becoming disabled messing around with drivers.)
