Hi all.
I am using the gpio_keys_polled driver to simulate a F20 key press. My
target application
a HTML5 application running in the browser on the target device will
read the keycode
via java script. The problem is that no MSC_SCAN is send from the driver.
# evtest /dev/input/event4
Input driver version is 1.0.1
Input device ID: bus 0x19 vendor 0x1 product 0x1 version 0x100

This is how i setup my button:
static struct gpio_keys_button device_gpio_keys[] = {
{
.code = KEY_F20, /* See include/linux/input.h */
.type = EV_KEY,
.gpio = 235,
.active_low = 1,
.desc = "F20",
.wakeup = 0,
},
};
Is there a way to also get the scan code?
thanks
