Hello,
I've got my Helios64 since a few week now and enjoying it a lot. I've installed k3s on it with various applications. The next step is to install home assistant to control my home. Previously, I've already had a setup with a RaspberryPi with a Arduino Mega connected, that is running the rflink firmware. That way I, can control cheap 433Mhz power switches.
The problem is, when I connect the Arduino (acting as a serial input device) to my Helios64, the system does not startup anymore. The following error message is printed on the serial console:
WARN halted endpoint, queueing URB anyway.
Unexpected XHCI event TRB, skipping... (f5f5deb0 00000000 13000000 04008400)

After this message is printed, the CPU is reset and the system tries to startup again.
Does anyone has an idea, what the problem could be? Does the system try to boot from the serial device?
I recently upgraded to Kernel 5.10.43, which did not solve the problem.
Many thanks for your help in advance
