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 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to usb-modeswitch in Ubuntu. https://bugs.launchpad.net/bugs/1866926 Title: usb_modeswitch does not switch modems (remain visible as mass storage) Status in usb-modeswitch package in Ubuntu: New Bug description: After upgrading to Ubuntu focal fossa development branch the usb_modeswitch does not seem to work any more on a Toshiba laptop. Two modems I have D-Link DWM-156 and Huawei E3372 show up as drives and stay like that until I use "Eject" in Gnome or explicitly use usb_modeswitch from the terminal. I have a strong feeling that it may either be related to Gnome or hardware. On another Dell laptop with Kubuntu focal fossa development, both modems connect automatically. /var/log/usb_modeswitch.log ends with: Warning: SCSI attribute "ref" not readable. Check class of first interface ... Device is in istall mode. No access to interface 8. Exit Up until and including the "ref" not readable is exactly the same as on Kubuntu @ Dell. Yet on Kubuntu I get plenty of successful config logs after that and on Ubuntu @ Toshiba I don't.
