Xavier agx can't use usb device after using upgrade?

Hello! We made a motherboard using xavier agx. After flashing our own driver, the usb interface can be used normally, but after using the upgrade command to update and restart the device, the usb device cannot work normally. Any solution?

You flash your own driver but you upgrade again with default jetpack drivers… so your own driver is gone.

So how to solve this problem?

Can you provide us with a better solution?

If you don’t need nvidia specific update, remove the /etc/apt/sources.list.d/nvidia-l4t-apt-source.list and do apt-get update. It won’t bring back the dead device but can prevent the future update/upgrade breaks other boards again.
