NetBSD's USB is unreliable on my hardware.  It works for some time, but after
some time a port or two may stop working until the next reboot.  A few weeks
ago writing to a CF card (using a USB reader) made this quad core machine very
sluggish, mouse pointer jumpy etc.  After a reboot, everything was fine again.

So yes please, if there's a working USB stack available, please port it over
:)
