1、Flash Jetson Tx2 using new JetPack4.2.1
2、Plug Usb-Hub on J19, connect USB Keyboard && Mouse
3、Login the system (usb keyboard && mouse work normally after system up)
4、Suspend the system manually
5、Wake-up the system, Press Enter on the keyboard.
6、this time, keyboard doesn’t work, only mouse work.
I do some test, Plug-out the mouse && keyboard, And Plug-in keyboard first, then keyboard can work correctly, but if I Plug-in Mouse First, keyboard can’t work. But dmesg can detect the keyboard plug-in, following is the msg output:
