Hi,
I've juste receveid a couple of Ltap LTE kits, with 2 R11e-LoRa8 pcie cards. I've first installed the cards like explained on the mikrotik docs: on the top pcie slot (named pcie1 + usb0), but the cards are not detected. It only work on the bottom slot named "USB 1 only". Is there a reason for that?

Thanks

Latest firmware? 6.46 or beta 6.47?

Sorry I forgot to mention it but it happens on both stable 6.46 and testing 6.47beta8

Try this command, it will switch the USB connection lines from the USB 2.0 port, to the miniPCIe top slot:

/system routerboard usb set type=mini-PCIe

It worked! Thanks a lot!
