I had a Buster setup that worked. The SD card failed. I now have Bullseye 32 bit on a new card. Full GUI.
I've put my Python application on it. And guess what? It doesn't run.
I use 2 serial ports : '/dev/serial0' which is connected to a serial LCD touch screen. As far as I can tell, this still works.
I then have a PICO plugged into the USB socket (not the power one). Using the same cable as before.
The Pi application should send a serial command via '/dev/ttyACM0' to the PICO which should respond.
However, I can't get the PICO port to open. And lsusb shows nothing connected.
I've checked the old cmdline.txt and config.txt files on the Buster system and my new Bullseye ones now match. But something would appear to be different between the two OS's.
I even tried messing around with dwc2 and g_serial (which were not present on the Buster setup) with no luck. Can anyone help.
