Modem can not detected after suspend / resume
- ModemManager 1.21.6 (local build ModemManager the latest code from gitlab main branch)
- Ubuntu 22.04, Kernel Linux 5.15.0
- Modem Type Quectel EM05-CN
I'm having an issue with using EM05-CN after putting computer into suspend status (command as 'systemctl suspend'). After system resume, ModemManager doesn't detect this modem, but lsusb shows that it's working. I don't have any issues with it after restarting the computer, or if I follows the sequences as below:
$ sudo systemctl stop ModemManager
$ sudo systemctl suspend
After system resume, restart MM as $ systemctl start ModemManager
, then Modem(EM05-CN) can be workable.
I have gathered the log https://modemmanager.org/docs/modemmanager/debugging/ as attachment. MM.logNM.logmbim.log
