3G usb adapter TPLink MA180 on v378.56_2 not working

[Khurram]

I am trying to get the 3G usb adapter TPLink MA180 work on Asuswrt-Merlin but not having any success. The service provider just requires an APN name (no authentication) and that is what I have entered in the "USB Modem / USB Tethering" page. But I think it is not even dialing as I dont see any pppd entries in the syslog. From the log, it shows that the adapter is being detected:

I tried the MA180 on another router running OpenWRT and it worked after a few attempts. The main difference is that OpenWRT creates 3 ports: /dev/ttyUSB0-2 and pppd connects on /dev/ttyUSB2. In Asuswrt-Merlin, only /dev/ttyUSB0-1 ports are created. gcom info -d <dev name> gives error on both these ports also. Is there something wrong with the detection of the MA180?

I have been searching for anwers to my problem. Over at usb-modeswitch forums, there is an old thread on the MA180 ( http://www.draisberghof.de/usb_modeswitch/bb/viewtopic.php?t=942). It also indicates that the modem is at /dev/ttyUSB2 which is not being created. In fact, the thread indicates that 4 devices should be created for the MA180. Is there a way to override the detection of the MA180 device ids and force the creation of /dev/ttyUSB0-2 ports?

Thanks.
