Cannot use deskpi-config in Manjaro 64 bit

[johntdavis84]

I didn't see this problem the last time I set up the DeskPi under Manjaro, but I just had to reinstall everything.

I get this whenever I try to adjust the fan settings via the script: sh: line 1: /dev/ttyUSB0: Device or resource busy

Here's the typical sequence:

./deskpi-config Welcome to Use DeskPi-Team's Product Please select speed level that you want: It will always run at the speed level that you choosed.

1 - set fan speed level to 25% 2 - set fan speed level to 50% 3 - set fan speed level to 75% 4 - set fan speed level to 100% 5 - Turn off Fan 6 - Adjust the start speed level according to the temperature 7 - Cancel manual control and enable automatical fan control

Just input the number and press enter. Your choice:2 You've select 50% speed level sh: line 1: /dev/ttyUSB0: Device or resource busy Fan speed level has been change to 50%

I'm not sure what to do to troubleshoot this. I've tested the front USB 2.0 ports with a USB 2.0 flash drive. It works fine.

lsof isn't showing anything using the ttyUSB0 interface.

I'm using Sway under Wayland.

I'm stumped. Any ideas?

hi @johntdavis84 Because serial port devices cannot be called by two applications at the same time, if one application is using it, you will see a "device busy" message if you try to operate it again.

Unless you stop one of the applications that are using it, currently when executing deskpi-config, if the background is already occupied by deskpi.service, the foreground cannot execute.

On the official Raspberry Pi system, if you execute the command deskpi-config, the deskpi.service in the background will stop, and you need to manually execute:

sudo systemctl restart deskpi.service

to restart the service.
