Basically, on the production boards they tied the usb power through regulators; two GPIO lines must be toggled to set the regulator or the usb power drops. For some reason the gpio mux lines controlling the regulators are left floating; not good.
There are two ways to fix it: 1) dts|dtb , or script , to toggle the mux lines turning the regulators ON, or 2) mod the board so that the regulators are ON all the time !
The regulators are on the schematic on page 19; We'll do some testing and see if we can get a software fix; otherwise, we'll put up a board mod procedure.
