Subject: Re: [PATCH] uvc: Intel PID enabling UVC Metadata attributes

Hi.
We have extended information about frame within metadata.
This information contains, generally,
hardware timestamp, frame number,
image sensor attributes and configuration,
firmware metrics etc.

You can follow source of RealSense SDK 
https://github.com/IntelRealSense/librealsense/blob/master/src/metadata.h

Please see attachments for lsusb for cameras:
405.0b5b.lsusb.txt
415.0ad3.lsusb.txt
430.0ad6.lsusb.txt
435.0b07.lsusb.txt
435i.0b3a.lsusb.txt
455.0b5c.lsusb.txt


All these cameras are multiple sensors USB cameras,
they are similar to already present 0x0b03 at uvc_driver.c

Regards,
Dmitry.
