Linux Lite on an old Mac mini

[kapitantan]

Hi.

I have installed Linux lite LTS on my old Mac mini.

I cannot get the wireless keyboard and mousepad running. The bluetooth device, although apparently running, does not identify their names.
However, the hw-probe reports that "Apple Inc. Bluetooth host controller" and "Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of BCM2046 Bluetooth)" both "work".

Any idea how to solve this?

Btw. why after installing Linux I still have an Apple Bluetooth host controller?

Thanks.
