It is already build with debug.
But I don't see anything of special interest in the output.

I will redo a test with raspbian.
Waveshare delivered a binary kernel (so much about GPL) for their 7" HDMI C
until they changed something in the device firmware and upgraded for a newer
panel about 2-3 years ago.
This is the 10.1" HMDI B and it is a very early version I have, which however
should use a firmware similar to the newer 7" HDMI C.
I will retest with a stock Raspbian image to be sure I wasn't accidently
using a Waveshare image back then.
As far as I can see the Linux drivers just quirk the device to the egalaxy
driver, so they do know the Waveshare by ID.
I couldn't spot a difference between Linux and what is included in the webcamd
source.
