RM520N-GL Module PCie Communication issue

HI Quectel Team
We are using the RM520N-GL module with a PCIe interface. The modem device is detected And showing active , but further communication is not occurring.
Below the Schematic pin configure M.2

I think you should change the mode from usb to pcie with at commands.

Modem Changed PCie mode only

If you are using openwrt, it will only run usb mode. If it’s in windows its ok with qnavigator

We are using the USB hub with RM520N modem please refer the below block diagram


but modem not detecting ,but we are connecting USB pen drive its detecting!
Please confirm any driver need to add this modem

are you using this?

We are using M.2 Connector assembled with Proto board this directly connecting USB HUB
when i was masking the USB 3.0 signal ,the USB 2.0 path modem detecting but both USB 3.0 and USB 2.0 not detecting the modem at time

Are you using openwrt?

No! we are using Linux

Openwrt cannot detect modem in pcie mode. I guess its true with linux since openwrt is lunux based. So run module in usb mode and install usb3 kernel files.

HI
Once masked the USB3.0 signal below logs coming but interface not creating can you help this?
