All those "#ifdef CONFIG_USB_OTG" lines you are sprinkling throughout 
the core are very annoying.  A few simple inline routines should allow 
you to eliminate many of them.

Also, in the 5/5 patch in hub_activate(), all those

        if (hdev->bus->is_b_host && type == HUB_INIT)

tests are distracting.  You can make the test once, at the start of the 
function, and store the result in a local variable.
