Macrosilicon MS2109 Dongle - The One I Have
This one is old and has very poor capture quality.
It maxes out at a heavily compressed 1920x1080 @ 30fps and the YUV 4:2:2
uncompressed stream did not work for me in 1080p mode.
tl;dr:

Clearly the coding chip in the dongle captures at a lower resolution or a high compression and everything fuzzes out.
I'd like to find a USB capture card that works better than this, ideally 1080p60.
