Установил на Raspberry Pi 4 Model B 4GB Alt Linux Workstation p10 через 
Raspberry Pi Imager (официальный образ). При попытке подключения к 
bluetooth-клавиатуре (через GUI и CLI) она сначала подключается на 
примерно одну секунду, а потом отсоединяется.

$ bluetoothctl
[bluetooth]# pair 34:88:5D:3C:07:D3
<ввод пин-кода>
Pairing successful
[bluetooth]# trust 34:88:5D:3C:07:D3

$ journalctl | tail -1
bluetoothhd[3682]: profiles/input/device.c:encrypt_notify() 
ioctl_connadd(): Protocol not supported (93)

Как я понимаю, проблема в ядре.

$ uname -a
Linux pi 5.12.17-rpi-un-alt1 #2 SMP Wed Feb 10 04:00:00 UTC 2021 aarch64 
GNU/Linux
(на ядре rpi-def точно такие же проблемы. Не смог проверить на std-def, 
так не подключился дисплей Waveshare 7inch LCD for Pi 
(https://www.waveshare.com/wiki/7inch_DPI_LCD), а HDMI кабеля нет в 
наличии).
