Passthrough works; capture device not detectedHDMI source path is present; USB enumeration/path is higher priority.Test HD60 X direct on a USB 3 host port/cable.
Device detected but black in all capture appsFormat/source/HDCP becomes more likely.Use a known unprotected supported source format.
DeviceOK/browser receives frames but OBS is blackCapture hardware path is partly proven.Check OBS source selection/resolution/other app contention.
Sequence
Work from reversible checks to escalation
- 01
Remove USB hub and connect direct.
- 02
Confirm a supported unprotected HDMI source.
- 03
Check capture device in browser/another app.
- 04
Match OBS source to the actual HD60 X mode.

When to stop changing settings
If USB enumeration/capture fails across known-good supported hosts and sources, use Elgato support.
