Sorry for the OT, but I did figure out a little trick. If you plug in the hub and power supply into Max3 without anything else attached and then reboot, it will be charging upon boot. Then if you insert the keyboard and mouse, it still wont work, only still charging... but if you are rooted you can "echo '1' > /sys/class/power_supply/usb/usb_otg" anddddd... viola! You have charging + OTG!
