Well, you're not doing something right, because point 3 of U11 is ground, there is no way on earth for that to measure 3.3v.

You really need a scope to see what's going on there for sure, but the meter should measure around 1.3v on pin 1, then 0.3v on pin 2 of U11, with the magnets in the Triggers away from the Hall sensors. You can also measure U10 for comparison, as it's the same Hall sensor, just for the RT instead of LT. If you have around 1v on pin 1, and 0v on pin 2, then that suggests either the LT line is shorted to ground somewhere, or the Hall sensor has gone bad.
You can check the Resistance across the RB button pads, and that should be a couple of Meg ohms or more. If the Resistance value is low, in the Kilo ohm range or lower, then it could be C29 or D3 on that board is bad. Remove both and test again, if the Resistance value is till low then I would suspect U4 on that board is bad.
Incorrect. It has pretty much the same outer shape as a miniHDMI connector, but that is a 19 pin connector. The one in the XB1 controller is only a 12 pin. I haven't gone looking for a mate for it, so hard to say what it is exactly.
