USB Capture not seen unless HDMI source is connected

  • I have a problem that when my Pi boots if there is not an active HDMI source connected to the USB capture loop then Hyperion won't see the USB Capture device.

    If I first plug in an HDMI source to the USB capture then boot the Pi Hyperion sees the capture and works.

    Has anyone else seen this and have a workaround?

    The USB capture is getting power from the Pi Zero via the USB cable.
