 With Q2E42D, I need to pull the cable to the external USB hub in order to
 (re)boot the XO.  I'm seeing this behavior with multiple machines.  [I've
 seen this also with Q2E42B and Q2E42.]

 With Q2E41, the boot process might have randomly (but rarely) stalled and
 required me to pull the cable to the external USB hub -- but those stalls
 normally were later (when trying to load the build), rather than before
 the message about the ok prompt ever got shown.

 I usually have an external keyboard plus an external trackball plugged in
 at an external USB hub.  [Sometimes an additional USB adapter or device as
 well.]  When I work with an XO, its associated external hub is plugged in
 at one of the USB sockets on the XO.

 If I am operating an XO, and wish to reboot (e.g., by typing 'shutdown -r
 now') -- if I leave the external USB hub plugged in when the boot process
 starts (I normally press 'check' so that I can see which device the build
 will be loaded from), with Q2E42D the boot process stalls after outputing
 "Using USB keyboard" to the console.  When Q2E42D stalls (and depending
 upon the XO), sometimes the 'power' light starts flashing red  (Q2E41
 stalling did not change the color of the 'power' light).

 My bypass is to power off the machine, unplug the external USB hub, and
 manually reboot.  [Without the external USB hub, booting proceeds as it
 should.]  It would be nice if the boot process were to avoid stalling when
 the external USB hub is plugged in.
