Ooh! Another place to test for a bootmode pin (i.e. "magic key" for usb downloader mode)! We just need a hacked USB cable plugged in while it boots, to see if it presents a freescale USB VID (15a2, as I recall) instead of a lab126 (1949, as I recall). If just a short, a standard OTG cable ought to do the trick. I will try that in the morning when no risk of waking spouse (3:40am here). I tried everything else. It is *possible* they are looking for a particular value of resistor across the USB OTG sense pin though (other than a 0-ohm short common in OTG cables), depending on the circuitry tied to that USB pin.
