Thanks for your answer Kai-Heng.
I am not sure what ftrace is. I used these commands to get the logs:

mount -t debugfs none /sys/kernel/debug
echo xhci-hcd >> /sys/kernel/debug/tracing/set_event
cat /sys/kernel/debug/tracing/trace

Can they be used to debug this? Or there is another procedure?

I understand that my device is different but I believe it has the same or very similar bug.
And I am seeking help. I don't know who to contact for this bug to be finally fixed.

Any suggestions are welcome.

Thanks.
