The tests with evdev go something like this: Code: .... fixme:dinput:joy_polldev joystick cannot handle type 4 event (code 4) joystick.c:353:X 0 Y 0 Z 0 Rx 0 Ry 0 Rz 857 S0 1984 S1 0 POV0 -1 POV1 0 POV2 0 POV3 0 B 1 0 1 0 0 0 0 0 0 0 0 0 fixme:dinput:joy_polldev joystick cannot handle type 4 event (code 4) fixme:dinput:joy_polldev joystick cannot handle type 4 event (code 4) joystick.c:353:X 0 Y 0 Z 0 Rx 0 Ry 0 Rz 1746 S0-1111 S1 0 POV0 -1 POV1 0 POV2 0 POV3 0 B 1 1 0 0 0 0 0 0 0 0 0 0 fixme:dinput:joy_polldev joystick cannot handle type 4 event (code 4) joystick.c:353:X 0 Y 0 Z 0 Rx 0 Ry 0 Rz-1286 S0-1429 S1 0 POV0 -1 POV1 0 POV2 0 POV3 0 B 1 1 0 1 0 0 0 0 0 0 0 0 joystick.c:358: joystick.c:379:-- Testing Direct Input Version 0x0500 -- joystick.c:202:---- /dev/input/event5 ---- joystick.c:134: Test failed: deadzone invalid: expected 0 got 235 joystick.c:134: Test failed: deadzone invalid: expected 0 got 235 joystick.c:134: Test failed: deadzone invalid: expected 0 got 235 joystick.c:134: Test failed: deadzone invalid: expected 0 got 235 joystick.c:278: Test failed: Number of enumerated buttons doesn't match capabilities joystick.c:328:You have 30 seconds to test all axes, sliders, POVs and buttons joystick.c:333: joystick.c:353:X-2000 Y-2000 Z 0 Rx 0 Ry 0 Rz-2000 S0-2000 S1 0 POV0 -1 POV1 0 POV2 0 POV3 0 B 0 0 0 0 0 0 0 0 0 0 0 0 joystick.c:353:X-2000 Y-2000 Z 0 Rx 0 Ry 0 Rz 968 S0 1762 S1 0 POV0 -1 POV1 0 POV2 0 POV3 0 B 0 0 0 0 0 0 0 0 0 0 0 0 joystick.c:353:X-2000 Y-2000 Z 0 Rx 0 Ry 0 Rz 1492 S0-1444 S1 0 POV0 -1 POV1 0 POV2 0 POV3 0 B 0 0 0 0 0 0 0 0 0 0 0 0 .... joystick.c:353:X -143 Y-1508 Z 0 Rx 0 Ry 0 Rz 0 S0 -270 S1 0 POV0 -1 POV1 0 POV2 0 POV3 0 B 0 0 0 0 0 0 0 0 0 0 0 0 joystick.c:358: joystick: 1263 tests executed (0 marked as todo, 16 failures), 0 skipped.
