I'm getting the impression that using the MPC880s internal USB support
might not be such a good idea.
If you can wait for an unspecified amount of time... hopefully not long (touches wood), full gadget & host support (assuming you have your propiatery 8xx board or development board properly setup) should be available.
Are there external USB host controllers that interface easily to an MPC8xx processor and have Linux support?

Perhaps there would be some way to get an MPC885-870 talking to an external Host controller, via some sort of CPM extension... to be honest, I haven't had a reason to look into that sort of thing.

The only real obstacle to using !MPC8xx-USB, is getting the Freescale part to talk to the peripheral chip properly. This would need to be done via an external BUS, somehow... however, I don't think that the mpc8xx series have such an external Bus interface.. hence why _persumably_ so much stuff is done on chip. Design of hardware is not something I'm competent to talk about... would your hardware design guy (or girl) not know the answers to this ?
