Glad you figured it out. I think I may add the double Tapped event as well as the custom button numbers since it shows up nice in the button controller app that way. Not sure when, but I do plan on adding it.
System driver only supports up to 2x taps I think, would register as doubleTapped.
There is no harm in leaving my driver enabled all the time, should perform just as good as the system driver but with the extra settings available.
Once the settings is on it should register as a button 1/2 doubleTapped event in the system driver, its not the same as my driver which uses extra button mappings. I cannot be sure if it works, I have never tested it, I only use my driver.
