let me clear this a little bit up. When __io_canceled is true, we are
terminating the connection to the HID device. In general this is done by
sending SIGTERM to the process. When __io_canceld is false then the HID
device cuts the connection. For the Microsoft devices this is after 12
minutes.

While I was playing with the Microsoft devices I found that the order of
closing the connections differ on who terminates the connection. I think
that the problem is on the Linux side, but I couldn't found it. If it is
really the fault of BlueZ it must be something very odd that we have
overlooked all the time.

Regards

Marcel
