bluetooth rock64 problem
#1
Question 
hello,

I had to set up my Rock64 a few days ago because the SD card had unfortunately died.
As always, I first installed a new SD card with the image "Armbian_20.02.1_Rock64_buster_current_5.4.20". Everything great. Only my bluetooth stick does not want to run.


I don't have a desktop version, only access via SSH


The stick is recognized, as before. Here are a few system information:

Code:
root@rock64:~# lsusb
Bus 005 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 002: ID 0451:16a8 Texas Instruments, Inc.

root@rock64:~# hcitool scan

Why is the stick not recognized with hcitool?
What else can I do?
What is missing ?

I wonder if you boot without the dongle plugged in and plug it in after the boot completes

ok
have now switched off the Rock64, pulled the dongle and switched on.


Code:
root@rock:~# sudo service bluetooth status
● bluetooth.service - Bluetooth service
  Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled)
  Active: inactive (dead)
    Docs: man:bluetoothd(8)

Now I put the dongle back in.

root@rock:~# sudo /etc/init.d/bluetooth status
