The vtopu FAQ for the product shows that the video portion has driver name "USB2.0 VIDBOX FW". That appears to correspond to an honestech device that looks quite different. honestech appears to be owned by VIDBOX, but VIDBOX was only created in 2015 and the device appears to date from 2012 or earlier. This is all confusing.

When I download the driver from vtopu and open the driver on OS-X I find that in the installer it calls itself "ezcap VIDEOGRABBER" and says that it is from EchoFX Inc, which appears to be https://www.echofx.com/ . That company does deal in video capture drivers for OS-X, but the product names it uses do not include VIDEOGRABBER.

I find a claim that "Easycap" renamed itself to ezcap . But that company claims to be a UK/USA company, and clearly the device you are looking at was made in China.

This is all confusing.

... Why this all matters is that at the moment we do not know if it is even possible to control your device from MATLAB. If we were to track down what device you have and the driver, we might be able to figure it out from driver documentation (if we can find any.) And if not from direct driver documentation, by tracking down what the device actually is we might be able to find a Linux driver that is compatible with it and read the source, perhaps by way of information at https://www.linuxtv.org/wiki/index.php/Em28xx_devices
