I already had a driver; it just was a little endian 32 bit one
and it needed to be rewritten to 64 bit/big endian.

And the development machine was also my internet gateway/desktop
so I had a fairly lengthy test cycle :-(

The UHCI/OHCI/EHCI documents can be found, e.g.,:

Fortunately, I didn't really need to understand the driver to make
it work.
