That's what I gathered from my USB book and the SiS 5598 specs. I do have one question about the 5598 and OHCI since I don't have the raw OHCI specs yet (if you have a URL handy it'd be appreciated). The 5598 has 4 registers starting at offset 100h to control the host controller emulation mode. Are these OCHI or is this 5598 specific? The chipset can apparently emulate a traditional keyboard and mouse interface from USB attached devices without even needing a usb driver, etc. I haven't tested it.
