Comment 90 for bug 1218973

Andreas,
Yes, you found the correct path to fix it.
Don't know why udev rules doesn't work every time.
BTW, you can add a file under /etc/modprobe.d/ to automatically remove hid_generic
$ cat /etc/modprobe.d/hid-rmi.conf
   install hid_rmi rmmod hid_generic ; modprobe --ignore-install hid_rmi
