Jetpack 6 Joystick Detection Issue on Nvidia Jetson Orin Nano Dev Board

Issue Overview

Users are experiencing difficulties with joystick detection while using Jetpack 6 on the Nvidia Jetson Orin Nano Dev board. Specifically, although the joystick is recognized by the system (as confirmed by the lsusb command), it fails to appear as js0 in the /dev/input directory. This issue typically arises during the setup phase when users attempt to integrate joystick functionality into their applications.

Symptoms:

• Joystick is detected via lsusb but does not show up in /dev/input as js0.
• Users are unable to utilize joystick input for applications, leading to functionality limitations.

Context:

• The problem occurs specifically when using Jetpack 6.
• It has been noted that kernel customization is a known workaround, but users are looking for simpler solutions.

Frequency:

• The issue appears to be consistent among users attempting to use joysticks with Jetpack 6.

Impact:

• The inability to access joystick input significantly hampers user experience, especially for applications requiring real-time control or interaction.

Possible Causes

1. Kernel Configuration Issues:

   • The kernel may not be configured to support joystick devices properly, leading to their absence in /dev/input.

2. Driver Issues:

   • Missing or incompatible drivers could prevent the joystick from being recognized correctly by the system.

3. User Configuration Errors:

   • Incorrect setup or configuration steps during installation may lead to detection issues.

4. Software Bugs:

   • There may be bugs within Jetpack 6 that affect joystick detection and functionality.

5. Environmental Factors:

   • Power supply issues or hardware defects in the joystick itself could contribute to detection failures.

Troubleshooting Steps, Solutions & Fixes

1. Verify Joystick Detection:

   • Run the command:

     lsusb
     

   • Confirm that the joystick appears in the list of connected USB devices.

2. Check Input Devices:

   • Run the command:

     ls /dev/input
     

   • Look for js0. If it is not present, proceed with further troubleshooting.

3. Kernel Customization:

   • If comfortable with kernel modifications, consider customizing the kernel as a workaround.
   • Alternatively, a simpler source build has been shared that addresses this issue without changing the kernel. Users can refer to this GitHub repository: GitHub – woawo1213/jetpack6-joy.

4. Install Missing Drivers:

   • Ensure that all necessary drivers for joystick support are installed.
   • Check for updates or patches related to joystick drivers for Jetpack 6.

5. Reconfigure Input Settings:

   • Review and adjust any input device settings in your application or system configuration files.

6. Test with Different Hardware:

   • If possible, test with another joystick to rule out hardware defects.
   • Alternatively, try using a different USB port or hub.

7. Consult Documentation:

   • Refer to Nvidia’s official documentation for any notes on known issues or additional configuration steps related to joystick support in Jetpack 6.

8. Community Support:

   • Engage with community forums or support channels for additional insights and shared experiences from other users facing similar issues.

Recommended Approach

Utilizing the shared source build from GitHub appears to be a successful solution reported by multiple users and is recommended for resolving this joystick detection issue without extensive kernel modifications.
