usb keyboard not working in single user mode

Hello

I've got 5.1-current running on an IBM BladeCenter HS20. This thing has 
a USB KVM built-in. It's working in multi-user mode. Problem is when I 
boot to single user, can't do anything.

I'm looking for a way to fire up the usbd in single user mode. So far 
I've tried:

Loading usbd.ko, ugen.ko, ukbd.ko modules via loader.conf. NO GOOD, 
hangs the system.
Setting /usr/sbin/usbd in /etc/ttys so that init(8) can run the usbd.

If anyone needs access I can supply a root login via ssh.

Thanks
