Questions[logitech](ubuntu)

Can you control things like viewing angle, zoom, fps, and video resolution for a webcam connected to Ubuntu, through a standard set of commands or API?

As a case in point, the Logitech Brio 4K Ultra HD. This camera seems to be advertised to allow adjustments of those properties that I just mentioned above, and I am wondering whether controlling them is accessible via any standard linux command-line (or standard programming API).

Typically I had good experience with all Logitech devices in Ubuntu but these features I've never experienced adjusting from/in Ubuntu.

Motivation note: I could use these features for acquiring indoors imagery for a machine learning project and the ability to adjust those properties could be important. That aside, these abilities might bear on how much all the sophistication built into this device actually leverages for quality in more mundane use cases like video chat.

I am a new ubuntu user and want to use my machine to it's full extent, so I looked for Logitech Options software for my Logitech MX Master 2s on linux, but found nothing.

Will the software run through Wine? If not, is there any other way to install Logitech Options or get to customize the functions of macro buttons and the thumb wheel?

Recently my Logitech c920 webcam microphone stopped working on my ubuntu 18.04. Microphone (input) recognized by system but not catching any sound. Skype and Cheese recognizing input but not catching any sound. Not hardware issue. When re-booting to Windows 10 everything working well. I am running out of ideas.

Logitech has a Unifying receiver that you can add several devices using the same USB device. Is this supported in Ubuntu and if so do I have to additionally configure something so that when adding a new wireless device it gets recognized by the same receiver.

Info: http://www.logitech.com/en-us/66/6079

I recently received a Logitech Rumblepad 2 (a joystick, like a PS2 controller) from a friend.

How would I configure this in Ubuntu? If possible, I would prefer to use a GUI utility.

I tried jstest-gui, but it shows my accelerometer!
