Review on Type-C/USB 3.0 HDMI Video Capture, 1080p@60fps Grabber - Game & Video Capture Device for Xbox, PS4, Switch, DSLR, Camcorders - Live Streaming Support, Windows & Mac OS Compatible. by Deron Gilliam

This is a nice product at a good price. The description states that it works on Microsoft Windows, Mac OSX and Linux. I tested it under Ubuntu 18.04 and 20.04 on three computers. Either it wasn't recognized as a USB device or it got disconnected when I tried to start capturing video. Only twice on one of the computers did it actually start capturing video, and then only when I plugged it into a USB 2.0 port and not the USB 3.0 port it was supposed to be plugged into. The problem is most likely that the USB implementation in the firmware is buggy. If they only tested it with Microsoft Windows, they might have removed as many bugs as necessary for the Windows USB driver. If this is the case, other drivers that issued slightly different (but perfectly correct) commands will fail because they find errors that have not been fixed. I really wanted to like this device and make it work. It worked twice, it produced good quality videos. But I can't fiddle around for an hour or two every time I want to start recording a video. The seller really needs to get the best firmware for this thing and set up a website for firmware updates. Until they do, and until they test it on every operating system they claim to support, I don't recommend buying it.
