Hey Everyone,
I'm still working on getting things set up and I think I might have a power source problem. Here's my rig:
Pi Zero
ZumYu HDMI Video Capture Card 4K
WS2812B LED strip
I've wired up a mini USB hub to connect my Pi to the network via ethernet (near the TV is a weak wifi spot) while using the main power supply. However, it seems that sometimes the capture card will pull power from the intended data connection rather than its own dedicated USB power connection. When it does so, the HDCP image will flicker, likely due to intermittent incoming low power.
This also happens if I try connecting directly to the Pi.
If I plug USB connections in using a "correct" order, the system works flawlessly.
Is there a way to force the video capture card to only pull power from its dedicated power source? Can I create a "data only" USB cable by clipping the power lines between the video capture card and the Pi or are the power lines needed for data transfer?
Just checking before I sacrifice another USB cable.
Thanks again for your awesome help!!
Phade.
