USB not detected in NVIDIA Jetson AGX Orin

I have 2 dev boards which I took out of the metal case. I placed it in a base I made and screwed the ORIN to the base.

I used this document ( Jetson_AGX_Orin_Series_Design_Guide_DG-10653-001_v14.pdf) as reference to the installation of the module (3.4 Module Installation and Removal).

The problem is when I place the screws, USB stops working in one of the dev boards. Without the screws it works fine.

The other dev board works fine with the screws.

Any suggestion?

Looks like the metal case when screwed might be touching or creating a short between the connector or some pins of the connector. Maybe, you could probe/check with a multi meter for any shorts.

It seems to be something related to that. We need to do more tests, but changing to a plastic case seemed to help. Thanks.
