I’ve got this usb key working on a CCR1016 and a RB3011 (creates lte1 as expected)
But It’s not working on RB2011 and CRS125
The key is detected in /system resources usb print but it do not seems to be used.
is this problem related to the mipsbe architecture ?
Is there a way to make it work properly ?
Amen to that!
I’m struggling to get it working myself for some time now.
I’m using a RB2011U (latest stable ROS & firmware 3.33) variant and generic(unbranded) Huawei M150-2. Once the modem is inserted in the USB its LED starts blinking oddly, and my RB is not recognizing it.
Funny thing is that the very same modem/SIM card combo is working with ZERO configurations on various other TP-LINKs… 
GJ, MikroTik!
Test to Reboot the router with the key plugged.
already test that,
reboot, plug, unplug, this is the kind of tests that goes without saying.
Also checked latest routerOS including development versions and firmware upgrade
The fact is that it works as expected on CCR1016 (tilera) and RB3011(arm) but not on RB2011 and CRS125 (both are mipsbe)
(didn’t check on x86)
