Works fine with only:

xboxdrv --evdev "/dev/input/event19" --evdev-keymap "BTN_SOUTH=a,BTN_EAST=b,BTN_TL=lb,BTN_THUMBR=tr,BTN_SELECT=back,BTN_START=start,BTN_THUMBL=tl,BTN_TR=rb,BTN_NORTH=y,BTN_WEST=x" --evdev-absmap "ABS_RZ=rt,ABS_RY=y2,ABS_RX=x2,ABS_Z=lt,ABS_Y=y1,ABS_X=x1,ABS_HAT0X=dpad_x,ABS_HAT0Y=dpad_y" --axismap "-y2=y2,-y1=y1" --mimic-xpad --silent

And evsieve version is 1.4.0.

Removing the ff argument when calling evsieve in ds4-xboxdrv.sh fixed all errors for me, I opened a pr: #3
