I just spent a few hours trying to figure out why my Alcatel modem wasn't establishing a connection...and ran across this bug. Thank you Hanno for the workaround!
I uninstalled the usb_modeswitch package and installed the one from Debian Bullseye, and my modem shows up now! After adding entries to my netplan configuration to enable DHCP, I can access the interfaces. -- 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: Confirmed 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.
