Definitely would be nice for this issue to go away permemnantly so we
don't have to keep digging out those trusty PS/2 or USB keyboards every
major upgrade.
I've dug into this little further...gained bit more understanding of all
this...and may have a proper solution...at least for MX5000 devices.
Just experienced this issue againthis time on upgrade to Precise
from 11.10. Coincidently, exprienced exact same issue with when trying
out Debian Wheezy/testing.
Also, worked is around the issue by changing the /lib/udev/rules.d/97
-bluetooth-hid2hci.rules from "hiddev*" to "hidraw*" for Logi
