so, DualShock ---> RPI ---> gimx, with config LogitechG27_G29.xml ---> USB converter ---> Arduino micro, with EMUG29PS4 ATmega32u4.hex flash. ---> PS4
for some reason it just refuses to work!!
I've been looking through the forums, wikis, tutorials and just can't find an answer

it got to the stage where gimx asked me to press the ps button... I press it and the PS4 acknowledges the button press, the RPI see's the input from the wheel as the mouse moves and menus pop up on the pi from the button inputs, but it won't control the PlayStation.
The DualShock controls the PS4 via the cable but the wheel refuses to do anything to it!
