Some PID compliant devices automatically play effects after boot (i.e. autocenter spring) that prevent the rendering of other effects since it is done outside the kernel driver. This makes sure all the effects currently played are stopped after resetting the device. It brings compatibility to the Brunner CLS-P joystick and others Reported-by: Jules Noirant <jules.noirant@orange.fr> Signed-off-by: Tomasz Pakuła <tomasz.pakula.oficjalny@gmail.com> --- drivers/hid/usbhid/hid-pidff.c | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-)
