Thanks for the detailed explanation, Warner. Interesting that on my
system hw.bus.devctl_nomatch_enabled=1 is set by /etc/rc.d/devmatch but
only explicit set it in /boot/loader.conf did the trick. That is why I
think this sysctl don't work in my case.

One more correction. Via kld_list I need load ums(4),
