RM520N-GL not responding

I have a RM520N-GL
I installed it in adapter (USB_TO_M.2_B_KEY) board, by waveshare.
Then connected to the USB3.x port
I am unable to detect the modem.
I have tried this in linux (dmesg, lsusb, lspci etc) as well as Win10 (device manager, other or modem or hidden devices)
The power LED on the adapter board is turned on.
However i am unable to see this under the operating system
Is there a way to reset the modem (it is a engineering sample)

Any other letters after -GL ?

Just posted a photo of it.
Looks like RM520NGLAP-M20-SGASA

Capture

GLAP is PCIe only

What would be the part number for USB verison
