Serial can't find my devices

[b135802]

OK let's see what is going on here. Please could both of you do this:

- Go to settings app and enable the debugging mode: https://openplotter.readthedocs.io/en/3....-debugging
- Plug in your non detected devices.
- Open a terminal an type: openplotter-serial
- Report here the output of the terminal

Have you tried with OP3 32bit?

First, sorry for the delay in response. I've been busy with some work issues. 

Without debug mode, no errors are printed on reply in terminal on starting openplotter-serial. In debug mode, the reply in the terminal is

Code:

pi@openplotter:~ $ openplotter-serial
wrong external apps format: unexpected EOF while parsing (<string>, line 0)
No module named 'openplotterMoitessier'
No module named 'openplotterMacarthur'
No module named 'openplotterOpenmarinebox'
No module named 'openplotterMaiana'
No module named 'openplotterSdrVhf'
No module named 'openplotterIot'
No module named 'openplotterNotifications'
No module named 'openplotterGpio'
No module named 'openplotterI2c'
No module named 'openplotterPypilot'
No module named 'openplotterAvnav'
No module named 'openplotterNetwork.serialPorts'
No module named 'openplotterDashboards.serialPorts'

I'm using a exteral powered usb-hub but tried several times with the RPi4's on-board usb-port to exclude errors from the hub too. The result is the same - openplotter-serial doesn't reveal any devices connected.

This is the 64-bit version, and I did't try the 32 bit version.
