Question / Help [Solved] OBS + AVerMedia Live Gamer Portable - device already in use

[Llamachan]

Hi guys,

I recently got an AVerMedia Live Gamer Portable. It's hooked up to my PS4 and then connected to my PC via active USB extension cable. When I try to add it as a source in OBS, I select properties in order to select the device, and then my PC makes a sound like USB has been pulled out and I get nothing through on the preview. I get the USB plugging in and out noise around five times before Windows 10 tells me:
"USB device not recognised -
The last USB device you connected to this computer malfunctioned and Windows does not recognise it."

The OBS log files (added at bottom of post) say "device already in use", despite it not being open in any other applications (that I'm aware of). I'm already using the 32bit version of OBS so it's not that.

If I open up the AVerMedia Stream Engine I can see my device listed with the correct settings, so the PC can see the device. I close this before trying to add it as a video source in OBS (so Stream Engine isn't using the device).

Things I have already tried:
- Uninstalling/reinstalling drivers
- Uninstalling/reinstalling Stream Engine
- Uninstalling/reinstalling OBS Studio
- Running OBS in admin mode
- Turning off preview whilst trying to add source
- Making source not visible and then visible again (with 'Deactivate when not showing' ticked)
- Closing Chrome and making sure it's not running in the background with Task Manager, same with Skype
- Unplugging USB, adding video capture device to my sources, then replugging USB and trying to configure it
- Setting the source device as both "AVerMedia C875 Capture" AND "LGP Stream Engine" (same result)
- Updating drivers on all my USB ports/hubs etc. through Device Manager

I think that's it... This is my second day of trying to fix it so I may have missed something else I tried! Does anyone have any ideas? Please! I've been Googling this like crazy and nothing seems to work for me.

Thanks.

Doesn't sound like it has anything to do with OBS. Try without the USB extension cable.

The PC is in a separate room to the PS4, the extension is needed to connect the two. What makes you think it's the cable? Genuine question, not arguing!

I can see the device when it's just hooked up and I'm not trying to add it to OBS, it's listed in Device Manager and through the AVerMedia software itself, so I assumed the cable was not the culprit, but I have no idea. Thanks!

Any sort of adapter or extension cable is suspect in a situation like this where connectivity seems flakey; testing with a direct connection helps determine whether the adapter/extension is at fault.

That does make sense. I guess I'll begin the arduous task of unhooking the PS4 from the mess of living room cables, moving it, and seeing if it works without the extension... It is a brand new cable, but certainly a chance it could be faulty. I'll update once I've tried it out.

You were right! Thank you for the nudge to actually test that. Took a bit of time to do but when it's hooked up directly it works perfectly. Have ordered a new (different make) cable.
