I recently bought what I believe to be the OEM version of the OSMC USB bluetooth dongle (LogiLink Bluetooth Micro USB 2.0 Adapter) since that's what was easily available around here.
I then disabled the RPi3 BT as per the instructions from earlier in the thread (dtoverlay=pi3-disable-bt should also work in config.txt) and rebooted. However even with the Bluetooth dongle plugged in I'm not getting the Bluetooth menu under My OSMC.
I guess that means the dongle isn't the same as the OSMC dongle after all and hence missing the driver, correct? Or what else could I have done wrong?
