Dose Jetpack support USB cable hotplug to wake up after os suspend?

Hi, JP5.1.2 developer guide lists the wake source included USB remote. I want to know whether Jetpack support USB cable hotplug to wake up after os suspend. So I tested in the following three ways:

  1. a keyboard is always plugged in;
  2. do not connect to a keybaord initially. After entering the suspend state on the GUI by the mouse, connect to a keyboard;
  3. keep a keyboard connected while entering in suspend state, then unplug and connect the keyboard again

Only the first way to wake up the os. Is this phenomenon normal?

I tested on Jetson AGX Orin devkit.

Hotplug usb device won’t wake up the board. Only usb keyboard can.

I may not have made it clear that the USB device I use to wake up the system is a USB keyboard. So is it normal?

請問你是在說你的USB keyboard只有在特定情況下可以叫醒機器嗎? hotplug之後無法?


So are you talking about USB keyboard can only wake the device in some specific situation? For example, it cannot wake device after doing hotplug?

Yes. I tested in the three ways mentioned above.

Does the power indicator of the usb keyboard still light up after you try the hotplug?

The power indicator of the usb keyboard is not on after trying the hotplug when os is suspend

Are you testing on NV devkit or custom board?

Both, and the results are the same as mentioned above.
I use ‘systemctl suspend’ order or GUI settings to make OS suspend.

Hi, do you have any information to share?

Is this still an issue to support? Any result can be shared?

Hi, 测试现象我已经说过了,我是想问我的测试现象是否正常

Yes it is normal behavior.

OK,thank you
