Info: Activate/Deactivate Pad code

[m4ss1m0g]

I must write a C# program to activate/deactivate the pad.

I downloaded the PCap file from Asus ProArt P16 Issue, and inside I found only one (interesting) SET_REPORT request with 0x01 0x01 data.

I write these values on the corresponding hidraw device, but nothing happens (no LED ON).

In your code, you open a handle to "/dev/i2c-x," representing the I2C bus, and send the codes 0x60 and 0x01 to activate the pad and 0x61 and 0x00 to deactivate, within a much bigger data array I post below.

I also found that necessary to load the i2c-dev with sudo modprobe i2c-dev load the /dev/i2c-x device necessary to run the code.

def send_value_to_touchpad_via_i2c(value):
    global device_id, device_addr

    try:
        with SMBus(int(device_id)) as bus:
            data = [0x05, 0x00, 0x3d, 0x03, 0x06, 0x00, 0x07, 0x00, 0x0d, 0x14, 0x03, int(value, 16), 0xad]
            msg = i2c_msg.write(device_addr, data)
            bus.i2c_rdwr(msg)
    except Exception as e:
        print(f'Error during sending via i2c: \"{e}\"')    

Where do you find this data to send to the device?

I attach here output file as result of probing the device with the appropriate tool on windows (https://github.com/bentiss/SimplePeripheralBusProbe)
