Hello,

I have a bunch of EU850D 3G modems which I've been using on RB411U since longtime.
Just tried them on a 912UAG-5HPnD but I can't see any serial device under / port. I upgraded ROS to the latest 6.5 and tried with a different modem card (same model), with no luck.

Do you guys have any suggestion?
Thank you.
Ciao.

Found the solution myself. FTR:

/system/routerboard/usb/set type=mini-PCIe

Marking as solved.
Ciao.
