Comment(by Quozl):

 John, I've checked on build 28 with q7b14, the GPIO 148 is configured as
 an output, and is set high, and the MFPR is set to function 1, and the
 ball number matches the schematic.  I've also tried to reset the hub using
 sdkit, while a USB drive was plugged in, and Sugar was displaying
 contents.  I observed no effects at all; no kernel messages, no change to
 the USB drive LED, no difficulty accessing filesystem.  This suggests that
 either it isn't connected, or it has no effect on the hub.

 I suspect the wakeup method used in testing is what runin is using; timed
