ah, interesting info.

ohci_hcd 23560 0
ehci_hcd 34692 0
ohci1394 35716 0
ieee1394 312376 2 eth1394,ohci1394
uhci_hcd 35216 0
To be honest, I do not know if I really need both uhci and
ohci; I guess not?

I'll do some tests the next days. Maybe I'll wait because I
just ordered a new USB-MIDI-Patchbay and I'd like to do the
tests with it, so I can ensure it does not depend on my
current Edirol UM-1S.
