I'm running Fedora 29 on a Ryzen 7 with an ATI Vega 64. Because Wayland's video screen capture abilities are terrible, I wanted to capture the HDMI output of my computer and feed it back the USB port for screen recording.This device worked flawlessly right out of the box. I knew that USB had bandwidth limitations, so while my screen is 4K, I told obs (Open Broadcaster Software) to use V4L and the device showed up immediately with no fiddling required. All the different capture modes showed up as well in the resolution selection. So I was able to get 1080p at 30fps with full color and it just worked.Few hardware manufacturers are willing to put in the attention to detail in their software so that specialized driver tweaks are not needed to account for ways in which their specific piece of hardware fails to follow standards specifications. Magewell deserves huge props for not being a manufacturer who is willing to do the work. This is how all hardware should be.
