I bought a couple of thumbnail-sized USB Bluetooth 5.0 adapters. Today I plugged one into a Rock64 board. I see ubt0 and bthub0 attach---great! `btconfig ubt0 inquiry` does not reveal my Apple keyboard.
Apparently the adapter I tried today (a TP-Link UB500) does work with Linux, however, a Realtek firmware blob has to be loaded. By the way, to interoperate with Bluetooth Low Energy devices, is anything beyond a compatible USB Bluetooth adapter needed? For example, kernel or utility changes?
