Question / Help Weird glitching with Avermedia Live Gamer Extreme [FIXED?!]

[JayEmPlays]

I recently upgraded my computer a bit, including a new capture card, from Elgato Game Capture HD to Avermedia Live Gamer Extreme GC550. When using it for recording with it's own software, ReCentral 3, it works just fine, but when I stream with it using OBS Studio 19.0.3 for 64 bit for Windows, it starts to have these weird glitches in the image. On TV it looks just fine, so it cannot be due to a faulty HDMI cord. Sometimes there's long breaks between the glitching, but they are weird and irritating especially when there's multiple ones on stuff like a simple loading screen of a game. I might even go as far as to say that there's a small bit of lag of the game due to this problem. EDIT: I can also report that it randomly freezes and requires a refresh on OBS and/or restarting capture process on capture card.

https://www.twitch.tv/videos/156879242 - on this highlight, you can see a example of the glitches from 1:17 onward.

So far I've tried the following:
- Capturing straight from the device
- Capturing a window of ReCentral 3 capturing the footage
- Uninstalling and reinstalling the Avermedia capture card drivers and ReCentral 3
- Using a friend's Avermedia Live Gamer Extreme
- Turning off all the other stuff from the display (followers, donations etc.)
- Updating OBS Studio (it says it's the latest version).
- Updated my graphics drivers
- Uninstalling Elgato Game Capture HD Drivers

What I HAVEN'T tried yet, should I?
- Un- and reinstall OBS Studio
- Suggestions?
- Turning off NVidia's Share/Shadowplay-function, as it sometimes starts running when OBS is on. I use it when playing Overwatch on my streams using PC to capture highlights.


I have included the log from the latest stream I had.

My Specs:
CPU: Intel Core i7-6700k @4.00GHz
MoBo: ASUS Z170 PRO Gaming/Aura (LGA1151)
Windows 10 64-bit
Graphics Card: MSI Nvidia Geforce GTX 960 (MSI) 2047MB
Ram: 16 GB DDR4
Capture Card: Avermedia Live Gamer Extreme GC550

Thank you for any help in advance!

*Bump* Really want this one solved, since the Avermedia Live Gamer Extreme also likes to crash when streaming with OBS.

Okay.
I fixed it.
I had plugged my Avermedia Live Gamer Extreme to a USB 3.1-port of my MoBo (Dunno what that really does). Switched it to a USB 3.0-port, and works just fine. I had a 15-min test run with it and while before it could've glitched at least 20 times in the same amount of time, this time there was no glitches. So I guess this is fixed?
