Hello Michael,

USB changes the speed according to the port status

Signed-off-by: Michael Trimarchi trimarchimichael@yahoo.it

I applied this series to the u-boot-usb 'testing' branch. When it compiles properly and no regressions are being detected, I move it to the 'next' branch for the next U-boot release.

Thanks.

Remy
