This module looks very interesting. I have tried to take the dongle apart but it is difficult to solder it properly to the board. Have you tested this module with IOIO OTG?
I think you should try to follow this example. http://ledpixelart.com/pixelv2board/ At least this was my intention but I could not find suitable module (which you have found).
