    Is there a list somewhere whith all the webcams that support led-control?

    It doesn't seem to work on my Logitech C525.

    Who has had any luck with led-control on their webcam?

    Thanks.

    Hello,

    I have took a look on the older (non ajax based control) revisions code and figured out the following:
    The LED handling stuff is handled by the following ioctls:
    V4L2_CID_LED1_MODE_LOGITECH
    V4L2_CID_LED1_FREQUENCY_LOGITECH

    This means that:
    - It has high chance that only Logitech cameras have LED control capability.
    - The LED controls are V4L2 controls, so they could be enumerated, so they should be shown up in the ajax based ui too.

    While I was learned at the university I have worked with a Logitech QuickCam Pro for notebooks, and if I remember well it had the ability to control the LED.

    Regards,
    Miklós

    The use of the led-argument is deactivated in the source of input_uvc.c - why?
