You don't need to change kld_list. In fact, you should undo any changes
you've made there. Undo everything in loader.conf you've done.
This is a bug in the boot optimization stuff. Or rather, this exposes a
long standing bug in the USB code where there's an asymmetry between the
nomatch events and the bus tree it presents to devctl causing devmatch to
fail when the nomatch events aren't present on boot.
Just set hw.bus.devctl_nomatch_enabled=3D1 in /boot/loader.conf and reboot.
Or update to the change I'm about to make.
