Connecting video grabber M.2 to Jetson Orin Nano

Hi,

We have a Jetson Orin Nano developer kit and we have connected a video grabber in the M2 PCie slot to take input from a couple of cameras.

The video grabber is the Eco Capture Dual SDI M.2 from Magewell.

We have installed the drivers for the Magewell video grabber but do not see the video grabber when we type ‘lsusb’ in the terminal.

Nor can we detect the cameras connected to the video grabber in /dev/video*.

The Jetson Orin Nano is running Jetpack 5.1.2

Are we missing any steps to enable the devices connected to the m2 slot? Does it need any changes in the device tree?
