Hi Chen-Yu,

Thank you for your reply. I've tested with and without the SPL gen3 changes
I posted yesterday on gen2 and gen3 boards. In all cases there's no power
to all three usb ports. The only other change I have in defconfig is 
adjusting the baud rate.

Mark Kettenis suggested I revert Patch 9/9 from this series and with
that reverted the one USB 2.0 port works again. Mark has a better
understanding of the issues and perhaps can comment further - cc'ed.
