Sometimes everything works as expected, the thumbsticks work OK and the touch-pad changes axis 15 & 16 (as reported by jstest). Other times axis 15 and 16 do not report changes, instead axis 0 is corrupted/changed when the touch-pad is 'swiped'. Evtest appears to report correctly all the time. It seems that the controller works first time it is plugged in (after boot), but then fails subsequent times. I think that the first time I don't get the pop-up message about battery being charged, which occurs on other times. I have not found a trigger yet, but was wondering whether others are seeing this. I am using a USB connected DS4 (no BT on this machine). OS is Xubuntu 13.10 with patched kernel, Simon. -- simon@slipstream:~$ jstest /dev/input/js0 Driver version is 2.1.0.
