(unknown charset) USB 2.0 ehci umass problems

Hi,


I've a usb 2.0 disc enclosure for 2.5 inch disk. It works great using
the standard usb stuff (1.x), but fails to use ehci (2.0). 

When i plug the usb 2.0 device i get the following output 

( hw.usb.ehci.debug=2 hw.usb.ohci.debug=2 )

Is there some hints or patches available to get this working?

with usb 1.x output no debug...

And works ofcourse.
