USB Devices Not Enumerated on Boot After Installing JetPack 6.2.2 On Jetson Orin Nano

Hardware: Jetson Orin Nano Developer Kit

JetPack: 6.2.2 L4T R36 Revision 5.0

After updating to JetPack 6.2.2, USB devices connected at boot are not enumerated. They only appear after a physical unplug/replug cycle. This is a regression - the same hardware and device configuration worked reliably on the previous JetPack version.

This is a blocker for my application, as the system operates headlessly and physical access after boot is not always possible.

What I’ve checked:

  • lsusb immediately after boot shows no USB devices

  • After replug, devices enumerate normally and lsusb shows all expected devices

  • Verified cables and powered hub are unchanged from working configuration

The issue you’re experiencing with USB devices not being enumerated after updating to JetPack 6.2.2 on the Jetson Orin Nano Developer Kit is a regression from the previous version. This problem can be attributed to changes in the USB configuration or initialization process in the new JetPack version.

To troubleshoot this issue, you can try the following steps:

  1. Verify USB configuration: Ensure that the USB configuration files, such as jetson-orin-nano-devkit.conf, have not been modified or corrupted during the update process. Compare the current configuration files with the previous ones to identify any changes.

  2. Check USB device tree: The device tree configuration might have been altered in the new JetPack version. Verify that the USB device tree entries are correct and match the hardware configuration.

  3. Inspect kernel logs: Analyze the kernel logs immediately after boot to see if there are any error messages related to USB devices. This can help identify if the issue is related to USB device initialization or enumeration.

  4. Compare with previous JetPack version: Since the same hardware and device configuration worked reliably on the previous JetPack version, compare the USB-related configuration files, device tree entries, and kernel logs between the two versions to identify any differences.

  5. Try a different USB port or hub: To rule out any issues with the specific USB port or hub, try connecting the devices to a different port or hub to see if the problem persists.

  6. Check for firmware updates: Ensure that the USB devices’ firmware is up-to-date, as outdated firmware might cause compatibility issues with the new JetPack version.

  7. Contact NVIDIA support: If none of the above steps resolve the issue, reach out to NVIDIA support for further assistance, as this might be a known issue or a bug in the JetPack 6.2.2 release.

In terms of comparing the Jetson Orin Nano Developer Kit with other Jetson modules, the USB configuration and initialization process might differ slightly between modules. However, the general troubleshooting steps mentioned above should still be applicable.

Here’s a comparison of the USB configuration for different Jetson modules:

  • Jetson Orin Nano Developer Kit: The USB configuration for this module is specified in the jetson-orin-nano-devkit.conf file.
  • Jetson AGX Orin Developer Kit: The USB configuration for this module is specified in the jetson-agx-orin-devkit.conf file.
  • Jetson Orin NX Series: The USB configuration for this module is specified in the jetson-orin-nx-devkit.conf file.

When comparing the USB configuration between different Jetson modules, ensure that the correct configuration files are being used and that the device tree entries match the hardware configuration.

In summary, the issue with USB devices not being enumerated after updating to JetPack 6.2.2 on the Jetson Orin Nano Developer Kit is a regression that requires troubleshooting and comparison with the previous JetPack version. By verifying the USB configuration, device tree entries, and kernel logs, you can identify the root cause of the issue and potentially resolve it.
