Dear Richard,
Please see the attached.
The attached image shows IO status when I was holding the R1 button.
It seems to work both R1 of DS3 and R1 of Flight stick at first glance.
When I push the buttons, the signs (R1) appears.
But actually R1 of Flight stick dose not work at all.
R1 of DS3 also does not work at all while connected to Reasnow S1.
When I use DS3 wihtout Reasonow S1, it works correctly.
Once I connect DS3 to Reasonow S1, R1 bottun does not work.
What should I do?
