> Disabling acceleration on scroll wheels of 3rd party mice

That's an issue with your mouse software.

> Want to use a 15 year old DSLR as a webcam over USB

OBS Studio can help or Elgato Cam Link if your DSLR supports HDMI.

Sounds like "You are holding it wrong"

Err, what software? I can set scroll wheel acceleration on ubuntu, with no additional software.

Using HDMI on my camera has a lower resolution output than USB, plus it has an overlay. Again on Ubuntu, USB just works.

Also have the same problem and my mouse doesn’t have its own software, it’s just a standard USB mouse.

So in a way, sure, it’s a problem with my mouse software. The stock one. :)
