1. Setup PS3 controller through cable pairing
2. Remove device from BlueZ's database
3. Plug original PS3 controller back
As we don't change the master bdaddr on the device itself, the joypad
will likely be trying to connect to BlueZ, and fail to connect after a
small period of time. But the device will appear connected just long
enough for the cable pairing to say "hey, I already have this setup".
Ideally, we would test for whether the device is temporary, or already
trusted, but testing for whether we've setup its internal services *and*
it's connected, rather than *or*, is sufficient.

This is still relevant. Szymon, could you please test this?
