Hi,
For my testing, I've got a computer with both a UHCI and OHCI
card. What I've noticed is that whenever I've got usb-uhci and
usb-ohci active at the same time, I end up with a crash (Opps). It
doesn't really matter because nowadays I make sure that only one HCI

The UHCI is a VIA card. I'm only having a IrDA dongle on it
(using irda-usb). Box is SMP PPro 150MHz.
