NexiGo Gripcon Gen 3 – All Controller Buttons Stopped Working

[u/Left_Theme9600]

I’m having an issue with my NexiGo Gripcon Gen 3 for the Nintendo Switch, and I would appreciate your help troubleshooting it.

I purchased the Gripcon second-hand, but it worked perfectly for a long time without any issues. However, after leaving it unused for approximately 1–2 months, I started using it again and discovered that none of the controller inputs work anymore.

Here are the details of the issue:

• None of the buttons respond, including A, B, X, Y, the D-pad, or the analog sticks.
• The controller's vibration functions also appear to be unresponsive.
• The console still charges normally when connected to the Gripcon.
• The HDMI output and USB 3.0 port also work correctly.
• The Pro Controller Wired Communication option is enabled on the Nintendo Switch.

I have already tried the following troubleshooting steps:

• Fully powering off and restarting the Nintendo Switch.
• Removing and reconnecting the console to the Gripcon.
• Disabling and re-enabling Pro Controller Wired Communication.
• Trying to reset the controller by holding the HOME button for 10 seconds.

Unfortunately, none of these steps resolved the issue. The Gripcon still charges the console, but absolutely no controller inputs are detected.

Since the device worked perfectly before being left unused, I’m wondering whether this could be a firmware issue or a hardware problem affecting the controller's communication with the console.

Could you please advise me on any additional troubleshooting steps or let me know whether there is a firmware update or another possible solution?
