The EHCI driver does some bounds checking when it's scheduling an iTD for
an active endpoint.  It sets the local variable start to
stream->next_uframe and moves that variable further in the schedule if
necessary.  However, the driver fails to do anything with start before
jumping to the ready label and setting the URB's starting frame to
stream->next_uframe.  Alan Stern confirms the EHCI driver should set
stream->next_uframe to start before jumping.
