To support firmware upgrade on webcam devices, currently we use Linux UVC driver extension unit controls (XU controls): https://linuxtv.org/downloads/v4l-dvb-apis/userspace-api/drivers/uvcvideo.html
Is there any equivalent libraries/APIs available in fwupd framework?
Thanks,
Sanjay

fu_udev_device_ioctl() if that helps. You'll need to have a superclass
deriving from FuUdevDevice.

video4linux subsystem supported by fu_udev_device_ioctl()? Our plugin is not getting invoked at all. How do we add video4linux device entry in our quirk file?
Here is the udevadm/v4l2-ctl output for our webcam device:

Thanks Richard. Quirk file attached. Also attaching console output captured with verbose logging (G_MESSAGES_DEBUG, FU_UDEV_DEVICE_DEBUG, FWUPD_PROBE_VERBOSE etc). We do see valid VID/PID/Serial/Name etc in raw dump of the device. But after invoking fu_udev_device_probe() for each video4linux subsystems, it throws "No detected devices" message. Let us know if we need to change quirk file, udev rules, conf files, update any Databases etc.
Thanks,
Thanks,
Sanjay

Hi Sanjay,
Sorry for the delay, I'm just back from PTO and processing all the
messages. Can you try the commit in wip/hughsie/udev-prober and see if
it helps? This should allow the instance IDs to be populated. If you
want to send me hardware that's fine too.
Richard.

Thanks Richard. That helped. We are in dev phase and gathering other requirements. e.g.:
Flag for video4linux subsystem, something similar to HAVE_IOCTL_H
Flag for video4linux subsystem, something similar to HAVE_IOCTL_H
Support for video4linux subsystem to set physical id (fu_udev_device_set_physical_id)

Yes, you need to check what the appropriate physical ID would be; I

think you can work something out pretty easily.
