Greetings,

During the installation of OpenBSD 6.9 on Raspberry PI 4 B, my USB stick was not \
detected and I decided to use microsd as the main disk. I also noticed that USB \
keyboard did not work either, so I hooked up a USB TTL cable to the GPIO pins and \
finished the installation just fine. Overall, it was a smooth experience !

Now, after the freshly installed system booted, I noticed USB keyboard & USB stick \
still did not work. There is a relevant message in dmesg, which suggests there is \
something wrong with initializing the USB host controller:

xhci0: reset timeout
xhci0: init failed, error=5

I checked the changes between 6.9 and current in here: \
https://www.openbsd.org/plus.html, but did not find anything relevant. How can I \
debug this further ?
