After a lot of research (credit to this thread), I can report back my experience with the N7100 for OTG and Charging at the same time.
My plan is to use the Note II in car, with audio out via USB, into an external DAC and then into my head unit. I will connect to a powered USB hub to access SD card/external storage as well as an EZCap device for Reverse Camera. A simple OTG cable permits this but there is no charging.
I bought these plugs to make my own cable ends. I created a regular USB micro plug - +ve, GND, Data+, Data- and then soldered a resistor across Pin 4 (ID) and GND. 64.9k triggers both Dock Mode and OTG. I only had a 68k and this worked fine as it's within the upper/lower tolerance range. The DIY kits allow for just enough room to fit a single resistor and is a nice clean fit in the car. The Micro USB connects directly to the powered hub and I spliced in a separate USB A male cable (+ve/GND only) for a spare power supply.
When docked, I use Tasker to run in car app (Google AutoMate), set the state/rotation/display etc; audio automatically routes to USB DAC, external storage is detected, EZcap works, and phone charges. Will need to monitor charge rate vs drain time but overall happy for the small outlay of connectors and a resistor...
