This issue has been reported multiple places by multiple people and a simil= ar bug report with a different capture card can be found here: https://bugzilla.kernel.org/show_bug.cgi?id=3D218943 In my particular case I'am using an Elgato 4K X plugged into my PC's USB4 p= ort which is directly connected to the motherboard. The capture device has been tested working at full speed in Windows 11. niko@Eva-Mini:~$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 2109:2822 VIA Labs, Inc.
