Player Index Selector Script

[hoover40]

My current setup has an x-arcade dual joystick and two controllers plugged into my pi. Sometimes I want to use the controllers and sometimes I want to us the x-arcade dual joystick. I want it to be easy and intuitive to switch the player index for the controllers. I think the easiest way to do this would be in the runcommand-onstart.sh script. I'd like to try to write it myself, but I'm not too sure where to start. This is what I think the simplest version of the script would need to do:

print "press a button on player 1 control"
listen for next input on all usb ports
save needed info from response
print "press a button on player 2 control"
listen for next input on all usb ports
save needed info from response
write info to appropriate config file

In the googling I've done I think I can figure out how to do most of these steps, but I'm lost as to how I should do the listen for input on all usb ports step. Can anyone point me in the right direction?

Is this way harder than I'm thinking it will be?

@hoover40 have you tried the RetroPie-joystick-selection tool?

It has not the exactly same flow as you described, but you can achieve what you want.
