VTS stopped being able to use my webcam a few weeks ago, need help fixing

[Sunneh]

A couple weeks ago, VTS stopped being able to use my camera (Logitech C615 HD Webcam). It worked perfectly fine with this before, but suddenly stopped. The light on the camera that shows when it's running does not come on when I select it in VTS. It works fine in all other apps though, and if I run it through OBS and use the virtual cam for VTS, it works - but that's obviously not gonna work when I wanna actually stream!

I've tried:
1. Restarting my computer
2. Reinstalling Logitech drivers
3. Reinstalling VTS
4. Switching off the VTS beta

Any other troubleshooting steps I can take here?

(And to be clear, OBS is not running and no app is using my camera when I'm attempting this.)

Can you try all of these?

And if that doesn't help, please open a thread in the VTube Studio Discord if you haven't already:

Best to remove the Logitech drivers and use Windows drivers instead. I have the Logitech C922, C910, C615, C515, plus a couple of others which I use in OBS. I have found the Logitech drivers can cause issues with a number of things when streaming. So I removed them all and no further issues.

If you are also using a number of Logitech webcams? They do not like being on the same USB circuit. So you need to ensure that they are on a different circuit. The same applies if using a USB HUB. Do not plug more than one Logitech camera into the HUB plus it is best that the HUB itself is powered.

Finally had the oomph to work on this. Like CybaGirl said, I have two Logitech webcams. If they are both plugged in when I start VTS, then VTS will not work. If I unplug one before starting VTS though, it will work. This started around the time of a LogiTech software update, so I'm guessing it's on their end.

I'm just happy it's working for now! Later, I'll try messing with removing the Logitech drives like Cybagirl suggested and exploring more of Denchi's thread as well, to see if I can find a solution that doesn't require unplugging one of my webcams every time I wanna do a Vtube stream. Thanks to you both!
