And I should mention that I had these timeouts with a different dongle
too (I switched from a bt 3.x dongle to a bt 4.x dongle around a year
ago). But as said, in the commit msg, the old behaviour might have
masked different problems like deadlocks or similiar too, so I just
might have experienced several different problems.
