Webcam fails on Linux

My external webcam and the internal webcam misbehaved on an Ubuntu 23.10 Try Ubuntu installation. Once the internal cam was not working, another time the external cam was not working. Multiple times, Cheese, the photo app, was unable to start at all.

I have a similar problem on Windows 11 (see my post FW 13 AMD not responsive when connecting monitor via USB-C - Framework Laptop 13 - Framework Community).

Can someone guide me how to trace the relevant message in the USB communication? I have the gut feeling something is wrong with my camera or USB firmware.

Device: AMD FW13, BIOS 3.03. Windows 11 latest, Ubuntu 23.10.1
