PCI, but still:

     ohci - OpenHCI host controller driver

     The ohci driver  is  a USBA (Solaris  USB Architecture)
      compliant nexus driver that supports the OpenHCI Host  Con-
     troller Interface  Specification  1.0a, an industry standard
      by  Compaq,  Microsoft,  and  National Semiconductor.

     The ohci driver  supports bulk, interrupt,  and
      control transfers.   ohci   supports  the nexus device con-
     trol interface.



I've had a USB card (first in my AXi, currently in my U30) for over a year
and a half.  It's a garden variety OHCI card purchased for $19.95 at

Works great with zip disks, printers, and quite a variety of interesting

Baloney.  SCSI DVD drives do tend to be more expensive, though.

It doesn't, not by any stretch of the imagination.  The SS20 bus design
was reasonable at the time but quickly fell flat.  Xbus didn't but was
relegated to the high end.
