Hi everyone,

I’m running into an stability issue with the USB subsystem on my DGX Spark and wanted to see if anyone else has encountered this or if it’s a known limitation of the current Hardware or anything from FW/Driver. To rule out cable issues I am able to stream, toggling on/off many time without issue on another Ubunut linux laptop.

The Setup:

  • Hardware: NVIDIA DGX Spark

  • Device: Intel RealSense D435i

  • Connection: Tested both Directly to the port and via a Powered StarTech Industrial Hub (Wall-powered).

  • Workload:

    • Standard RGB stream (640x480 @ 30fps) using the Native V4L2 driver (I did try RUSB driver also and it failed the same way) whenever turning on both RGB + depth
    • Also crashed if toggling on/off with only RGB only from realsense-viewer

I am having a similar issue with one of my DGX sparks. I can SSH and SFTP to the box. RDC will not connect. Nor can I get the Gnome Desktop to boot There are text errors that are displaying through the KVM display. My other DGX works fine through both RDC and the KVM.

How do I recover from this?
