Yes, I wrote the current OHCI support, based on some initial patches by Gianni. I found OHCI to be much easier to deal with than than UHCI. The low-level bits of the USB protocol are fairly nasty. UHCI is a cheap and nasty host solution, which directly exposes (and requires faking of) all the nasty low level details and timing. OHCI is a higher level interface which I found makes it much easier to actually implement things sanely in a virtual environment. > So we'd definitely need to work on OHCI if it's important for some > platforms. I consider OHCI to be important. x86 is abut the only target foolish enough to use UHCI.
