Would you be able to enable debugging for the hid subsystem to get some
debug data when getting the version from the device fails?
I can't see any problems in there that wouldn't also have impacted all
the other Logitech Bluetooth devices listed in the support devices
list.
If the problem is a timeout, maybe we should lower the timeouts we
currently have (5*HZ = 5 seconds, right?), so we can retry 5 times one
second instead.
Still, as I mentioned earlier, I can't reproduce the problem on another
Bluetooth Classic device...
