[ 1720.456001] uvcvideo: Found UVC 1.00 device HD Webcam C615 (046d:082c)
[ 1720.671480] input: HD Webcam C615 as
/devices/pci0000:00/0000:00:16.2/usb5/5-1/5-1:1.2/input/input16
[ 1720.671674] usbcore: registered new interface driver uvcvideo
[ 1720.671679] USB Video Class driver (1.1.1)


Shouldn't it say "Found UVC 1.10 device"?
It is a UVC-1.5 device.

As far as I recall the values that appear in those log strings come
from the data provided by the device. What does this show?

$ lsusb -v -d 046d:082c | grep bcdUVC

Then it looks like the driver is correctly reporting what is in the
camera's descriptor data.
