To further clarify the impact of different hardware on bug occurrence: The difference in Mariusz' hardware (Dell vs. Toshiba) leads to different kernel names ("3-4" on Dell vs. "2-1.2" on Toshiba). So "device validation" only happened on his Toshiba (thereby updating iface to the wrong value of 8), but not on Dell. Similarly, I had a problem on RPi 3 (kernel_name = "1-1.3") but no problem on an x86_64 VM (kernel_name = "1-1"). My hardware and VM both ran on Ubuntu 20.04 LTS.

This is the commit that fixed a segfault in the C dispatcher but introduced the problem for Mariusz and me: https://git.launchpad.net/ubuntu/+source/usb-modeswitch/commit/?id=4ef455d6d34fa465945db2b18f5dcabc604a9888
