Because a working, rigidly mounted camera can function as an edge 
detector, yes, it becomes a valueable part of the calibration setup for 
the machine.  But when actually operating, the camera has no direct 
control over it. In fact, I've made provisions to remove it so it 
doesn't get in the way once the measurements are made and recorded.

The machine would only notice it was crushing the camera when it crowbars 
the 5 volts from the usb port. That would generate a big frownie and 
some unprintable language directed at the guy in the mirror.

Perhaps you could investigate running the camera on something running
buster or later, rather than on the wheezy machine.
I assume you're not using the camera to actually control the mechanism
being run by the wheezy machine.

One possibility down, two are remaining.
To recap:

1) "quirks" parameter of uvcvideo.
2) Upgrading to buster.

I hear that, L & C. I did a lot of stuff in C and ARexx, on the Amiga 
25-30 years ago.  Rusty doesn't even come close to describing me now.  
It wasn't any help to my thinker when I had a pulmonary embolism 6 years 
back. I don't recommend that as a way to die. Survival rate is about 2%.

That won't happen until the developers get all the kinks worked out of a 
new 5.x.x kernel and RTAI.  But they are busting ass trying to make it 
work for buster as I write this...  Wheezy's semi-original 3.4.9 kernel 
was the last time it was stable. Even that claimed it was PAE capable, 
but never was, so its best with only 2 gigs of dram in a machine if you 
want to keep it out of swap.

And thats the sort of machine this camera has to work in.

This, combined with [1], gives us the probable answer.
Another possible answer is that "quirks" parameter of uvcvideo.

> Anybody have an idea of what driver this camera needs?

A *driver*? You already have one, it's uvcvideo. It says so in your
dmesg, plain and clear as a day.
Much better question is - what *userspace* part the thing needs? And the
answer to that is:

apt-get install uvcdynctrl

If stretch's uvcdynctrl won't cut it - that means you'll need buster's
one, or maybe even bullseye's. And that will require upgrading your OS,
of course.

  usually new devices lag drivers in linux enough that if
you are not running a more recent kernel you may not get
it to work.

  might be worth trying with a newer kernel or a more
recent distribution.

  that's all i can suggest.  :)  gl...

I understand you very well - it might be this one liner is from the time of
wheeze as I used back then (wheezy jessie) a dvb tuner and webcam scanner a
lot. I was also looking recently and found out some of it was not working
on the newer hardware and came to the above solution which I put in another
script. IT might be it depends on the video driver (for the hardware) in
use.
Unfortunately I am not a VLC user and can't tell you how to do it in vlc :(

I'll give that a try, but it really has to run on a wheezy install, using 
camview, which has the target structure for precision point location 
built in.

it is obviously UVC, but I think might be your driver does not support the
device yet

Recently, I was unable to access a camera through Shotwell, but was able
to with gwenview through /run.
Looking at the readout, I don't think this is workable, but it may be
worth a try.

The v4l2ucp (video for linux 2 usb control panel) should be able to

That sorta works, video refresh rate at 640x480 is about 1 frame a 
second, and if any camera motion, has severe window shade effects.
Not plugged directly into a usb3 mobo port however.  Color etc seems good 
though.

Hi Gene,

try to use your camera with mpv player. Just use something like this:

$ mpv av://v4l2:/dev/video0

My camera works just fine with Skype, Zoom and Hangouts but it doesn't
work with VLC.

Kind regards
Georgi

Doesn't have a card, usb only, and worthless as machine vision if you

[Gene Heskett]

Greetings all;

Just got a new camera, fawcny endoscope, I intend to use for machine.

Moderately high priced, 5 Megapixel, autofocus.

But this stretch machine can't find it amongst all the other usb stuff.
It doesn't have cheese, and vlc doesn't recognize it.
