(added Marcel to CC)

This means that something (I guess that it's hid2hci command?) is trying 
to pass through hiddev a value in a field that is greater than a given 
bitmask (and is not going to fit into the bitfield).

Vincent, does the problem go away when you don't use bluetooth (both 
keyboard and mouse is switched to HID mode, if they support it)?

Marcel, do you have any idea how this could happen?

Thanks,
