Question / Help Issue streaming with OBS when 360 wireless receiver plugged into PC

[seephor]

I am facing a strange issue with OBS and it only occurs when I have the 360 wireless receiver plugged into my PC. When I go to Preview/Stream, OBS will freeze and end up "Not Responding". If I unplug the receiver and try again, then it works. What could be causing this? Anyone else experience this? Windows says all my drivers are up to date and I am running 64-bit OBS as admin. I tried with 32-bit as well. I am running on Windows 10.

Thanks and here is the log file:

How many webcams?
Are you using usb hubs?

I am using two webcams and both work when I don't have the 360 receiver plugged in. No USB hubs.

Just did a little test. I can have one webcam on while the receiver is plugged in, but not both. Why is this? Too many USB devices?

USB bus bandwidth is finite. Webcams use a *lot* of it, especially at higher resolutions and/or framerates. For example, 1080p@30fps video technically will not fit over USB 2.0; most 1080p cams will do minor on-device compression to make it fit, but not much as it's computationally expensive to compress, then decompress on the computer side. A single Logitech c920 will swamp a host controller when run at 1080p. Double 720p cams could as well, especially with other devices on the same chain.

Try switching your cams to separate USB Host Controllers (in the Device Manager you can switch to 'view by connection' then drill down to your USB hosts, and see which are connected to a shared controller).
