I have a pretty old and pretty buggy modem. The QMI interface does not work reliably, so i want to use ttyUSB2 (at) instead. Is there a way to tell ModemManager to use that?
Also is there a way to tell it to only use it IF the model number is MC7304?
One possible solution is to blacklist cdc_wdm, but i have not found a way to blacklist conditionally (based on modem model number).
