 The XO-1.5 has USB ports available internally in addition to the three
 external ones.  One of these (port 5) is connected to the WLAN connector,
 and the other comes to a pair of 0805 resistors R392/R393 (with the other
 pads providing power and ground).

 Running firmware q3a15b and os39, Linux did not see a USB peripheral (a
 keyboard) connected to the R392/R393 port (USB port 4).  The same
 peripheral works fine when wired to port 2 (an external port).

 R392 provides +5VSUS and D+. R393 provides GND and D-.
