Autocenter is a default effect playing on the device following power up or reset. It is disabled by stopping all effects. On at least some devices (all?) it is a spring effect playing in slot 1. Capturing Windows USB packets reveals it dinput acquire does (1) a reset (this enabled autocenter) and, if autocenter is disabled, (2) a stop all effects (this disabled autocenter).
This logic works regardless of whether autocenter is a spring effect playing in slot 1 or not. It does mean autocenter can only be set when the device is not acquired. Testing on Windows reveals setting autocenter properties while acquired returns DIERR_ACQUIRED even if the device is exclusively acquired, so this is consistent. --- dlls/dinput/device.c | 4 +--- dlls/dinput/joystick_hid.c | 3 +++ dlls/winebus.sys/bus_sdl.c | 4 ++++ dlls/winebus.sys/bus_udev.c | 20 ++++++++++++++++++++ 4 files changed, 28 insertions(+), 3 deletions(-)
