Elgato HD60X vs Stream Deck Software

Hi!
I have an Elgato HD60X capture card and I’ve been experiencing a strange issue when using it alongside a Stream Deck (any model).

The problem:
When I open the Stream Deck software, the capture card starts restarting on its own nonstop. If I close the Stream Deck software, everything goes back to working normally.

How I identified the issue:
The capture card is next to me and starts blinking continuously, followed by the sound of USB devices disconnecting and reconnecting in Windows.

Current setup:
Both the Stream Deck and the HD60X are connected directly to the PC, without a USB hub, and using their original cables.

What I’ve tested so far:
I tested with both the Stream Deck Mk1 and the NEO — the issue occurs with both. I’ve also tried different USB ports and even used a hub, but nothing worked.

What I’ve already tried to do:
I contacted Elgato and even sent them a log, but they asked me to let the issue run for over 5 minutes. I’m worried this might damage my HD60X if it keeps restarting for too long.

Does anyone have any idea what might be causing this issue or how to fix it?
