Feature request: Add LTE modem support MHS291L (MHS291LVW)

Device:
WikiDev
Official

When connecting device we get:

Vendor ID 0x10a9
Device ID 0x6080

it is in ZeroCD mode, no ports. Need to switch it to modem mode (like usb_modeswitch does), to get

Vendor ID 0x10a9
Device ID 0x6085

Also would be nice, to support “Diagnostic port”, qcserial.ko in Linux

This would be nice.

Not sure if it was done yet, Im trying to use a 291L and it wont work on my CRS125-24G

Does anybody knows how to make it work?

Hi
I really need this.
A customer of mine has a few of these, and they will move to Mikrotik if I can make them work as Internet backup for their branches.

I would help on anything if needed.

Still waiting.
Any hope on this?
