The original CPM USB controller was only supposed to be
a device side controller. With some software hacks, CPM
microcode downloads, and even some hardware modifications,
you can often get it to work as a host in some static situations.
It doesn't have a built in root hub, you usually concentrate
on making it work with one specific device for a particular
product. You may find some application notes on the
Freescale web site, but I haven't seem them lately.
Take Wolfgang's advice, it's easier to find a way to
attach a real USB controller than to make this one
work as you probably expect.
Thanks.
