I would like to run DVI2USB 3.0 using linux (ubuntu 18.04). So I have downloaded the linux driver from epiphan’s website, installed it, and signed it as described in https://blog.ubuntu.com/2017/08/11/how-to-sign-things-for-secure-boot. The driver loads, the LED of the DVI2USB goes from red to blinking blue, and a new device video1 is added.
Using it with VLC to capture and display the video does however not work. I get the following error messages:
VLC is unable to open the MRL ‘v4l2:///dev/video1’. Check the log for details.
Enabling VLC’s logging function gives me this log::
