Try the following C code:
| #include <stdio.h>
| #include <fcntl.h>
|
| int
| main(int argc, char *argv[])
| {
| char buffer[3] = { 1, 3, 0 };
| int fd;
|
| fd = open("/dev/ugen0.2", O_WRONLY);
| if (fd < 0) {
| fprintf(stderr, "Cannot open device\n");
| return (-1);
| }
|
| write(fd, buffer, sizeof buffer);
| close(fd);
|
| return (0);
| }
I'm currently toying around with the headset, so I've disabled the
uhid(4) driver, so the LED on the gamepad keeps blinking. Running the
application above turns off the LED. I guess it should also work when
you write it to /dev/uhidX.
