Dear All,

I am trying to use "usb keyboard" on u-boot. I am using the
u-boot stack which was shared by you. Can you help me to know where problem
is going. I am sending some of debug prints which i found on my "Beagle
board xM".

I have connected usb mouse and usb keyboard on same side of port, here usb
mouse lights up but the keyboard does not powers on. Both keyboard and
Mouse are from logitech.

Please help me to make this up as i have scheduled demo.
