Hi, I have a RB953GS-5HnT and I am trying to use it with two sierra wireless MC8775 3G miniPCI-e cards. I have a problem that the card in the second slot (the one not shared with USB port, the one closest to the SFP ports) is not recognized at all. I tried the same card in the first slot (closest to Ethernet ports) and (after setting the USB mode to mini-PCIe) I can see the card as usb2. But when I plug it in the second slot nothing shows in the USB ports. Is there some setting that I need to adjust or is my brand new routerboard, which I just bought, defective? I tried two different MC8775 cards in the second slot and neither one is recognized.
Mikrotik software version is the latest - v6.27.
Thank you
