Unfortunately kbdrate affects all connected devices and I am not sure if
there is a utility allowing to set rate on individual devices. But here
is the main part:
static int input_set_rate(int fd,
unsigned int delay, unsigned int period)
{
unsigned int rep[2] = { delay, period };
if (ioctl(fd, EVIOCSREP, rep) < 0) {
perror("evdev ioctl");
return -1;
}
return 0;
}
