USB-Focus-V3 connexion problem was created by philippe.revellat@free.fr

I am my new USB-Focus-V3.
I create on EKOS a new profile with only CCD simulator and my USB-Focus-V3.
Using EKOS I start INDI and obtain image USB-Foc-001 (No connexion of the focuser)
I go to Tab Connexion ( image USB-Foc-002)
In the tab Connexion I click on : System Ports, Scan Ports and Enabled (Auto search) ( image USB-Foc-003),
I go on tab Controle Principal and Clic on Connecter image USB-Foc-004 image USB-Foc-005 ).

I don't obtain the connexion.

What must I do ?

The correct port is probably /dev/ttyACM0 but a common issue with this device is ModemManager think it is a modem and immediately take exclusive control on it, so INDI cannot open the port.

The solution is to remove ModemManager (you probably not use a serial modem for a long time):
sudo apt remove modemmanager

BTW the web page for this focuser www.indilib.org/devices/focusers/usb-focus-v3.html is seriously outdated, it still point to the obsolete Cloudmakers driver and the only useful information is in a review by Han last year.
How is it possible to update this page?

Patrick, you can now edit and publish documents on the website, so you can go ahead and update the documentation. I already did , but it would be great if you or any other user can share screenshots for each tab and fill the rest of the driver documentation in as well.

Thank You. As you wrote I enter the command sudo apt remove modemmanager and after I can connect the focuser easily.

For me the problem is solved. It will be important for the other user to have an updated documentation, but how to do this?.

Thank you Jasem.
I will add information and screen shot as soon I recover my home internet line that was broken by a thunderstorm today. At the moment I use a slow mobile phone and this is very inconvenient.

Philippe, I will update the documentation, no problem.
Now it is connected it must work fine. I use it for auto-focus every clear night.
In the case you get error message about incomplete command or value you can solve them by increasing Option/Polling period form 500 to 1000.

I have updated the doc.
Please tell me if you see other point that can be useful. I am so used to this focuser now that maybe I miss something.

One useful addition to the udev-rule is also create a symlink in case there are also other devices using ttyACM*, mine is:

SUBSYSTEM=="tty", ATTRS{product}=="USB_Focus", SYMLINK+="focuser", ENV{ID_MM_DEVICE_IGNORE}="1"

so it's always /dev/focuser
