Hello,

One thing you can try is removing one of jumpers J5 and J6, then connect the board. If that doesn't work, try the other one. Let me know if either configuration works.

You are correct in guessing that the slave mode works like a SL811S. We had a developer get slave mode to work at one point under MicroC/OS-II. I'll see if we can get that code to you as well.

One side-effect of the way the board is wired up is that some of the USB power makes its way to other areas of the board when connected to a USB host. Don't count on it to power the whole board reliably though.
