The choices are a bit limited for a true host controller. We are
using a Lucent USS302 (UHCI) part on a uClinux/ColdFire design.
This is a PCI part, and we are using an Anchor/Cypress CO-MEM Lite
PCI bridge to provide the PCI interface.

I have the PCI bridge working under uClinux, providing the standard
PCI bios functionality. We are working on back porting the USB stack
from Linux 2.3.51 to 2.0.38 of uClinux now.

Have a look at the board at:
