twinstick maple plugin not picking up twin stick controller help?

I have a DC twinstick but using the twinstick maple plugin it is not picking up twin stick controller via a mayflash usb adapter and there is no option to map controller?

If I go into demul emulator i can map everything other than the right stick and it works on those controls in virtual on DC game but when i use the actual twinstick plugin on NULLDC I get nothing is there anyone who knows how to get it working?
