I am running freebsd 10. Setting hw.usb.ehci.no_hs=1 at the loader prompt leads 
to the following usbconfig (with no devices available). 

ugen1.1: <EHCI root HUB Intel> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) 
pwr=SAVE (0mA)
ugen0.1: <EHCI root HUB Intel> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) 
pwr=SAVE (0mA)

That's really frustrating. Maybe I have to buy pci usb host controller and try 
again? Or is this not a hardware related problem?

Try to set:

set hw.usb.ehci.no_hs=1

In the loader prompt before booting, if you are running 11-current.

--HPS
