The USB dongle is based on MacroSilicon MS2109 ASIC that’s not yet listed on the company website. An analysis of the UVC data shows supported video capture resolutions range from 720×576 to 1920×1080, and metadata from captured video reveals the dongle will auto-synchronize to the video refresh rate.
