I gave up on Bluetooth and Linux, made sure the wireless peripherals I wanted had 2.4ghz dongles. Been using Logitech 2.4ghz lightspeed for a while. Dongle is plugged into a hub mounted under the desk. Use piper to get all my Logitech mouse features. No complaints.
Would continually run into disconnect issues with Ubuntu and Debian with all my Bluetooth devices. Got tired of tinkering with it.
