I am attaching the relevant syslog output captured while the serial USB devices are being detected and probed by NetworkManager. I also added the output of /lib/udev/nm-modem-probe --verbose --export /dev/ttyXXX0 for each port.

As shown in the log, both ttyUSB1 and ttyUSB2 report GSM capabilities, but only one (if3) does work. The other (if1) either crashes the modem or does nothing.

The patch I posted fixes this by checking the value of the --vid and --usb-interface parameters passed by NetworkManager to nm-modem-probe so that the "wrong" interface is ignorred and only the right interface is displayed to the user.
