Public bug reported:
https://packages.ubuntu.com/bionic/kernel/linux-modules-4.15.0-196-generic
file kernel/drivers/media/usb/gspca/gspca_sonixj.ko
in this driver, the illuminator est considered driven by the sensor chip.
i buyed recently an hercules (guillemot) webcam with illuminator .. 06f8:3008
the illuminator dont work.
found the sonixj.c driver source ... webcam are considered as a coupling of two
main chips
-a sensor chip with an array of photodiodes which creates the image
-a controller wich processes the image and sent the the image on the usb line
found the tech_ref of the sensor chip = NO pin to drive any led.
so, the led is driven by the controller (logic, no !)
made some modification on the sonixj.c source, build it, it works for my
webcam on an very old asus L5D (athlon 64 processor - first generation)
** Affects: linux (Ubuntu)
Importance: Undecided
Status: Incomplete
** Patch added: "modified sonixj.c tou allow illuminator for webcam 06f8:3008"
