Banana Pi Router design BPI-R4/BPI-R4 Pro(MT7988)

As title, I’m using the latest ‘supplied’ fw but my Quectel RM551E-GL 5G card is not recognised or found in any of the M2 sockets (USB only or USB/PCIe sockets) on the top of the board.

I read there is possibly some issue about USB not being found, but could someone advise me…

You have to make sure pcie lanes are switched to key-b…in my dts aply the overlay for the right pcie slot (cnX)

Thanks. Could you elaborate a bit please?

Also, I want to use a usb connection to the RM551E-GL, not Pcie, if possible…
