MM selects the first port that passes probing as the main port (except for Huawei modems where it always uses USB interface 0), unless it's been "tagged" according to the udev rules. Some modems only allow PPP on specific USB interfaces, and for those we have to find the Windows driver and look at the .INF files for which interface is supposed to be the "modem" or PPP interface. Note that USB interface numbers don't directly correspond to the X in ttyUSBx (or ttyACMx). What modem is it that you're having trouble with? It may be as simple as getting the Windows driver and figuring out what the port mapping is supposed to be.
