Hello

Just acquired a routerboard 433uah and upgraded to v4.9 stable. I have been following the wiki for usb 3g modems and have have become stuck at port print command. It only shows the serial port and not a port for the usb modem. Yet under system resource usb print, the 3G modem is listed. Someone did as the question under v4.6 but that was not answered.

I hope someone can help here?

Thanks

Try to unplug and plug the modem,
test RouterBOARD with another modem (the same model).
As E220 listed as supported on wiki page,

If still no port shown, Pos firmware issue (revision).. ??
