Elo USB touchscreen stop working after system reboot

The USB touch function stopped working every time we reboot the Jetson Nano, it will start working after we plug out and plug in the USB cable to the Jetson Nano’s USB port.
Sor for we have tried to use a different USB port on the same Jetson Nano, also tried it on another Jetson Nano, still the same problem.
Can you help me to identify what might cause this problem?

Is it a nv devkit or some custom carrier board?

What is shown in dmesg when you connect the usb touch and boot up?
And what is shown in dmesg after you plug out and re-plug the usb touch cable?

Compare the log between these two should tell you what happens to the driver side.

Hi, thanks for your reply, it’s the developer kit. I’ll try to your solution and get back to you.
