I actually tried to build the cable i was referring to in my first post. It worked on my galaxy note 3 but not on my tab S tablets, I guess the kernel trigger charging a bit different on the tablet. Anyway for some Samsung units it looks like you can work something out. I saw someone had soldered 5v/A directly to the micro usb port on the ioio board. Would that work?
I also tried different dongles last night and it was a bit better with a 4.0 but it is still to slow. I have been searching like a mad man for a solution and I still do just wanted to ask again if someone recently came up with an idea. "Alternatively, if you don't need 1kHz sampling rate, you can reduce it using a one-line change in firmware." How do i go about to change the sample rate?
