Computer unable to detect nRF54H20 devkit

Hello,

I am trying to program a simple sample application to my brand new nRF54H20 devkit.

I followed all steps at https://developer.nordicsemi.com/nRF_Connect_SDK/doc-legacy/latest/nrf/app_dev/device_guides/working_with_nrf/nrf54h/ug_nrf54h20_gs.html

But my PC is unable to detect the Devkit when plugged in.

nrfutil device list 

shows no device found.

If I plug in my nRF5340 devkit, it immediately recognizes it.

The devkit flashes green/yellow led when I connect a USB A to USB C cable to DEBUGGER port. 

Any pointers to how I can proceed/debug would help.

Thanks,
Dhara
