Considering that there are also other USB issues (the external port not working for data), I think this is clearly a USB issue, not a modem issue.
I have a PPpro where the modem comes up on most USB but not as a sound device, through all of the firmware changes.
but I can see in the modem's dmesg that it is not able to create the sound device. Even flashing to stock doesn't fix the issue. Frustrating as I just bought this replacement system board.
