USB serial not working with Bullseye Minimal/Regular CLI version (stops working after initial setup)

Hi,

I've installed minimal cli version and it restarts when connected to PC via on-board USB-C connector. Board hangs after:

[  OK  ] Reached target Hardware activated USB gadget.

Host computer does:

On regular CLI version it seems to work for now. Or in fact it stops working after initial setup!
