Only after reading the discussion of you with mdf@ concerning that 
commit, I realized that I have kern.hz=100 in /boot/loader.conf, too, 
and that never before caused trouble for me using USB devices, either.

I got that from http://wiki.freebsd.org/TuningPowerConsumption while I 
was on 7 or 8 , but I guess power consumption tuning should be different 
on 9 with the new timers and I have to rethink that, soon.

That Wiki page should be changed, if the recommendations are in 
violation with proper USB functionality.

Anyhow, does that change anything? Shall I increase kern.hz before 
anything else?

Cheers,
