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. -- Dan
