The ORIN NANO USB2.0 Interface is Dropped Abnormally, and the Kernel Reports an Error: LIBUSB_ERROR_OVERFLOW

Issue Overview

Users are experiencing intermittent USB disconnections while utilizing the USB 2.0 interface on the Nvidia Jetson Orin Nano Dev board. The symptoms include random disconnects of connected USB devices, particularly a camera, which are logged in the kernel with messages indicating a device disconnect followed by a new device connection. The issue occurs approximately every few hours during normal operation.

Specific Symptoms:

• Kernel log entries report:
  • usb 1-3: USB disconnect, device number 5
  • usb 1-3: new high-speed USB device number 6 using tegra-xusb
• The camera operates normally upon reconnection, suggesting a temporary loss of connection rather than a permanent failure.

Context:

• Software Version: JetPack 5.1.3
• Hardware: Orin Nano Devkit
• The problem does not occur with USB 3.0 connections or when using the same camera with other devices (such as PC and TX2 NX).

Impact:

This issue can disrupt workflows that rely on stable USB connections for real-time applications, particularly in scenarios involving camera data acquisition.

Possible Causes

• Hardware Incompatibilities: The USB 2.0 interface may have compatibility issues with certain devices or cables.

• Power Supply Issues: Insufficient or unstable power supply to connected devices could lead to disconnections.

• Software Bugs or Conflicts: Bugs in JetPack 5.1.3 may be causing instability in USB handling.

• Driver Issues: The drivers for the USB interface might not be fully optimized for the Orin Nano Devkit.

• Configuration Errors: Incorrect settings in the system configuration could lead to communication errors.

• Environmental Factors: External factors such as temperature fluctuations or electromagnetic interference might affect USB performance.

Troubleshooting Steps, Solutions & Fixes

Step-by-Step Instructions:

1. Check Power Supply:

   • Connect the USB device to a powered hub before connecting it to the Orin Nano Devkit.
   • Monitor if disconnection issues persist.

2. Update Software:

   • Upgrade to JetPack 6.0GA, which is the latest release for the Orin series, as it may contain bug fixes and enhancements.

3. Test Different Cables and Ports:

   • Use different USB 2.0 cables and ports to determine if the issue is cable-specific.
   • Verify functionality with known good cables.

4. Monitor System Logs:

   • Use the following command to monitor kernel logs for any recurring errors:

     dmesg -w
     

   • Look for patterns or specific error messages when disconnections occur.

5. Adjust Camera Settings:

   • Modify the camera’s data transmission settings (size and interval) to see if it affects stability.
   • Test configurations like (8k,0s), (16k,125us), etc., as mentioned in user tests.

6. Isolation Testing:

   • If possible, test the Orin Nano Devkit with different USB devices to see if the issue is isolated to specific hardware.
   • Run tests in different environments (e.g., temperature variations) to rule out environmental factors.

7. Documentation and Updates:

   • Consult Nvidia’s official documentation for any additional troubleshooting steps or firmware updates related to USB performance issues.

Recommended Approach:

Connecting through a powered hub has been suggested by users as a potential solution that may stabilize power delivery and prevent disconnections.

Unresolved Aspects:

Further investigation may be needed into specific driver updates or patches from Nvidia that address this particular issue with JetPack versions prior to 6.0GA. Users are encouraged to report back on their experiences after implementing these solutions for ongoing community support and knowledge sharing.
