There are two bluetooth devices paired with my main computer. The connection is via this dongle: $ lsusb ... Bus 003 Device 003: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) Two devices are paired: $ bluetoothctl paired-devices Device C0:15:DA:B9:77:39 Bluetooth Ergonomic Mouse Device 3B:0C:40:C7:35:16 TEWELL T-1 Both have problems:
The MS Ergonomic Mouse often doesn't connect when the system starts. Sometimes it's possible to get it to connect by running $ bluetoothctl connect C0:15:DA:B9:77:39 but generally the only way to get the it to connect is by running: $ sudo pkill bluetoothd which kills the bluetooth daemon; another instance is automatically restarted, which recognizes the mouse. Also, the mouse often falls asleep; it's possible to wake it by moving it around, but it would be nicer is it stayed awake.

The TEWELL internet radio often cuts off the first part of sentences when listening to voice. I can post a recording if anyone wants to hear.
