What device is it you're using specifically? Can you not see it in OBS as a Video Capture Device at all? Device Manager's listing it as 'working properly? Are you attempting to run that device from the same internal USB hub as other devices and perhaps exceeding power draw?
The device should enumerate in Windows as "USB Video". If that looks ok, can you get it to initialise in anything like VLC or MPC if you open the capture device directly?
An OBS log would be helpful. Please post a log with the device connected. (Help > Log Files > Upload Current Log File, and paste the URL in so we can all examine).
Some caveats around these cheap USB HDMI capture devices:
Some of the devices advertised as USB 3.0 are not actually 3.0. (examples here.)
I also own some USB2 HDMI capture devices with the MacroSilicon MS2109 chipset, they can only do 1080p25/29.97 with fairly average quality (MJPEG only - no 50/60fps at 1080p, only 720p).
Also worth noting that with the MS2109 devices, by default their sound is also incorrectly presented to Windows (improperly interleaved 48 kHz stereo is misinterpreted as 96 kHz mono). This is due to a well-discussed bad implementation by the manufacturer which is not inherently fixable. There is a workaround for Windows called "mono-to-stereo" and an ALSA quirks patch for Linux users.
