Thanks your config helped me to track it down. Looks like I got
the PHYs the wrong way around between EHCI and MUSB..

In any case, I did have omap-usb2 compiled in, but I did not have
OMAP_OCP2SCP=y set. Should OMAP_USB2 depend on that?

Also, looks like MUSB just sits in b_idle mode though, so no more
ID pin interrupt for some reason.
