Hi,
What is the proper way to disable the LEDs on the Quick Cam Pro 9000 and
You must use logitech extension controls for this,
you can use uvcdynctrl from libwebcam (command line) or guvcview
(gtk), you must be root to add these controls to the driver (libwebcam
installs a udev script to handle them automatically).
Do you have an example?
There are no examples in the man page.
Ah found this:

It fails:
# uvcdynctrl -s 'LED1 Mode' 0
ERROR: Unknown control specified.
Thoughts?
Got it:
# uvcdynctrl -i /usr/share/uvcdynctrl/data/046d/logitech.xml

Will have to check the LED later, thanks.
