I recall I read back then that this is imposed by Apple - you have to do something with them - license or verify or whatever and the drivers are for Mac only - as I said - it is the same chip inside the DVB that works fine in linux or windows. I don't own a Mac, but I would not wonder if this is the case. The DVB Stick for Mac was 30,- $ more expensive. regards

It's typical for standards-compliant hardware to work well on Linux, Windows and Mac OS without issue. When it doesn't, it's probably not standards-compliant. StarTech has a reasonable reputation for both honesty and compatibility: if they thought that a given device could work without a specialized driver (in this case, UVC standards compliance), then they would claim it on the package and in the manual. Since they don't, I expect this device does not support UVC. -dsr-

When I was looking for DVB-T Stick, I found that the same chip is used in a different model especially for the Mac and then found out that it is typical for Mac hardware.

UVC device.
Hi, This device is an analogue video converter. https://www.startech.com/AV/Converters/Video/usb-3-0-video-capture-device-hdmi-dvi-vga~USB3HDCAP The output should be UVC compliant. https://en.wikipedia.org/wiki/USB_video_device_class Yet guvcview reports "no video device found".
