I need Linux usb driver and udev rules for RG200U-CN mini pcie module as with default kernel 6.1.55 lsusb down not show Quectel modem

Show the output of cat /sys/kernel/debug/usb/devices
No pictures please.

It is because the hwdb do not support the RG200U, but it doesnot matter.
There is no such udev rules.
Please check

cat /sys/kernel/debug/usb/devices
ls  /sys/bus/usb/drivers/
ls /lib/modules/`uname -r`/kernel/drivers/usb/serial/
ls /lib/modules/`uname -r`/kernel/drivers/net/usb/

Technically you have no modem, it’s too early to talk about drivers.
Make sure your modem is properly connected and powered.

One more info, Quectel EG25-G works fine on the same platform, for RG200U-CN i don’t see usb serial device. I am expecting usb connections are pin compatible between both mini pcie modem.

8

Can i get link of HW design document for RG200U-CN mini pci module?

Please make sure with lsusb we can see the 2C7C 0900.
If you cannot see the VID and PID of the RG200U, and it means there is som hardware issue.

Please check the Quectel_RG200U-CN_Mini_PCIe_Reference_Design_V1.1.pdf.
