Bryan,

EHCI does not work on ES1.0 silicon. this is a h/w issue. we had 
implemented a workaround on the board where the USB port that were 
connected to EHCI were re-routed to OTG and OTG was configured in host 
only mode... this is how mouse/kbd used to work on ES1.0 board. With the 
latest defconfig with EHCI enabled, it cannot work on ES1.0.
