Bug Report Logitech c920 and Windows 8.1

cstafford1800 · Feb 17, 2014

Been having issues got a c920 for valentines day and I cant seem to get it to show up in OBS. Seem there have been issues reported all over logitechs website and pretty much every case involves windows 8.1. Im not sure if this is an OBS issue since Skype seems to have issues too but I love this cam and I know that Jim does too which is why maybe you know a solution to the issue. And I know my Bit rate is really really high Im not streaming yet just using it for File output and I know to turn it down when I start to stream.

Seems like you're getting some generic USB problem.. Try a different UBS port or plug the cam directly if you're currently have it connected over a USB hub and make sure to recreate the video device source after doing so.

cstafford1800 · Feb 17, 2014

No this has nothing to do with it Ive used different ports has nothing to do with usb cause the cam works within its software

cstafford1800 · Feb 17, 2014

So got it to work not sure what i did but its working

aromans · May 23, 2015

Can you explain what you did? I am having the same problem. The camera isn't even turning on.. It is very frustrating

Harold · May 23, 2015

Does it work in 64-bit obs?

No, thats what I am trying it in. I am plugging it in USB 3.0 ports, but shouldn't that not matter? It seems like it is though..

Harold · May 23, 2015

In your case, does the camera work in other programs (both 32-bit and 64-bit if you can test them)

No, unfortunately I tested the webcam on an older computer that has USB 2.0 ports, and it worked on there. So apparently, the Logitech c920 does NOT work with USB 3.0 ports... I also can't seem to find any adapter or converters to change USB 3.0 to 2.0

Sapiens · May 24, 2015

USB 3.0 ports are backwards compatible with 2.0 devices, and concluding that the webcam doesn't work with USB 3.0 ports when your only test was on an entirely different system doesn't make any sense. The C920 should work fine with USB 3.0 ports, in Windows 8.1, in both the 32-bit and 64-bit versions of OBS. Logitech provides the necessary DirectShow drivers in their webcam software package, which you should install/reinstall if you haven't already.

If that doesn't fix it, and the problem occurs in other programs like Skype too, you should be talking to Logitech support.

That's incorrect. While USB 3.0 is supposed to be backwards compatible with USB 2.0 devices, often times you'll run into compatibility issues. This pops up into a bunch of different ways. The devices will reconnect off and on randomly, degraded performance, or the device wont even show up.

USB 3.0 doesn't just 'work' like USB 1.0/2.0 did with each other. This is why a lot of motherboards include USB 2.0 ports still (putting aside bridge chips). Perhaps this will be fixed in USB 3.1, but right now a lot of bridge chips and even Intel implementations still have issues with compatibility with older devices. None of my USB 2.0 peripherals work with my 3.0 ports reliably. I've tried this on a few different motherboards. The exception to this being my USB 2.0 mobile dock. It depends entirely on the motherboard/peripheral/bridgechip though.

If you want to convert from USB 3.0 to 2.0. Buy a USB 2.0 hub and use that in between the devices, that works for me most of the time.
