This sounds like:
6881952 devfs occasionally failed to update the ownership of some USB
HID devices
If this bug was hit, there will be some error messages in
/var/log/Xorg.0.log*:
(EE) Xf86OpenSerial: Cannot open device /dev/usb/hidX
Permission denied.
and ls -lL /dev/usb/hid* will show that the device is owned by root.
I haven't tried to reproduce this on snv_122, but it's reproducible on
snv_123.

This issuse sounds another:
