The thing I would most like to see in an updated Diablo is a way of optionally running USB host mode with OHCI and EHCI controllers in place of the currently built-in MUSB.

This looks like the best hope for overcoming Bug 3281. The bug isn't "Fixed in Fremantle", but it is a serious limitation on N8x0's usefulness. With that fixed, I might be able to leave my 770 at home when travelling.

For end users, there would have to be some indication that the USB operation is host-only when this option is active.
