ehci is usb2, ohci is usb1. if the device is usb1 (and there are only _very_ 
few working usb2 soundcards on linux), it will always show up on a ohci-bus.

If it worked in this combination before, some update ruined it. If it never 
worked before on this machine, it might be because some usb-devices share the 
bus. Or because the usb-controllers share the interrupt with something else.

Have fun,
