Thank you, i'will try that.

Is this rules file necessary for all DMK cameras? or some? At any rate, if it is required I will add it to INDI.

Hi,
Unfortunately, this have not change.
In fact in my first message i make a mistake. The all black image was that of an another webcam (basic webcom) witch is identified like /dev/video0 and connected on my computer.
The DMK is identified as usb device (with lsusb) but in /dev there is no corresponding device.
When this another webcam is connected, it is identified as /dev/video0 and when i select DMK in Ekos, Ekos accept to connect but on the webcam instead of DMK. If i unplug the webcam, Ekos can't connect the DMK and there is no /dev/video0 device in /dev.

This is surprisingly common, I had exactly the same issue with a Celestron Neximage 5 and Ubuntu. The NI5 i basically the same camera as the DMK41 AU02.AS.

The issue is that,although Linux detects the camera, UVCVideo doesn't take ownership of the device when it is plugged in, and doesn't create the /dev/video* module. There's a good thread on it here:
The solution I found to work (after many hours of googling ) was to re-flash the Neximage 5 with a firmware from The Imaging Source. The Neximage 5 still works with MS windows and iCap after the re-Flash.

There's a step-by-step guide here:for obtaining the flash update and applying it which worked for me. The update backs up the cameras original firmware and also gives steps on how to re-apply the cameras original state.

If you decide to try it, be sure it is relevant to your specific camera model, and good luck!

Would someone please write a summary of the HOWTO so that I add it to the DMK INDI Device page. It would help prospective users from dealing with this issue from scratch. Is there also any permanent solution?

Give me a couple of days, I'll write a step-by-step guide from my experience with the NI5.

Hi everybody,
Always the same problems with indi/Ekos/Kstars
It's impossible to connect correctly my cams (DMK21AU04, inova PLC-M and Orion StarShoot G3 Color...
Only my Atik 314 L+ is ok
I want to transfer my observatory from WINDOWS+ASCOM+ASTROART to UBUNTU+INDI+KSTARS+EKOS but for more than a year i try to find solution!! And nothing new...indi can't work with these cams.
Is there a somebody in the indi's guys who can ask to the manufacturer to write a correct driver for their products...
DMK : The different solutions I saw about the DMK are not really reliable. Some time it work some time not.
inova : when i install the indi_inova_ccd driver (Ubuntu), Kstars don't recognize the PLC-M and if i try to use the driver with Indi/Ekos, Kstars disappear of my computer (2 time today !!!), and it's lot of command to be able to reinstall it.
Orion : nobody on the web seems to be able to connect it with indi...
All of these products work well on Windows and ASCOM ...
So i will continue to manage my observatory with Windows (burk) and ASCOM (yeahhh!).
it's a shame because Indi and Ekos are really nice ...

Please, Is there somebody who can tell me a real and reliable solution (i have no enough money to buy 3 others Atik!) for these cameras with indi?
thank you in advance for you
