USB Controller Support

The Apple Macintosh USB system software supports controllers compatible with the Open Host Controller Interface (OHCI) specification. It does not support Universal Host Controller Interface (UHCI) controllers.

Some early USB devices (most notably keyboards) can't interoperate with an OHCI controller. These devices will not be supported by the Apple USB system software.
