Sierra Wireless MC7355 not working

Hi,

I just bought 2 x 912UAG-2HPnD to use Sierra Wireless MC7355. These show supported hardware for Mini-PCIe. I tried two different cards but they dont show up either PCI or USB under system>resource. No LTE, no PPP. Nada. I tested the cards with a Linux device and it worked perfectly before I put them in the mikrotik.

I have emailed mikrotik support with a .rif file, but they have not responded. Any suggestions would be welcomed. Thanks.

Chris
