After a clean install (not upgrade) of 13.0-RELEASE the problem is still there.
It still looks like bus contention to me. Another way I can stop the ucode
loading is to add to /etc/rc.local the following
/usr/sbin/usbconfig -u 0 -a 3 power_save 

Without powersave, with no usb devices plugged in, and cold start, is a useful
workaround.
