I can get the MX2 to work with my atrix 4g dock using just an HDMI and this http://www.amazon.com/gp/product/B007RFRHIY/ref=oh_details_o02_s00_i00 usb cable (don't think its OTG).
The USB is going between the male dock USB and the OTG port on the MX2. I get power and touchpad/keybd work.
But I have the crappy resolution selection. With this set up I cannot boot with the lid closed - blue light comes on and I can hear the speakers pop, but when I open the lid it looks like the dock cuts power and the turns it on again.
Question - why do you need to use the dock std USB port to power the MX2? Does the OTG cable disable the ability of the OTG port to power the MX2?
The MX2 currently needs the 5v to POWER the device FIRST then also you need the OTG to enable keyboard and track-pad.
