Question / Help OBS causing USB ports to disconnect/reconnect

I'm basically copy pasting another post because i'm having the same exact issue, the only response was t hat this was a hardware issue which is incorrect.

"While streaming, suddenly my mouse, keyboard, webcam and headset m icrophone will suddenly all disconnect/uninstall, and I hear that disconnect sound that Windows makes when a device is removed. Then, I get a popup saying drivers were installed for my usb devices. This occurs again and again, and only occurs while streaming. The only thing I can think of to do is to reinstall/update the drivers for the usb ports on my motherboard, but this didn't stop the issue."


My keyboard when it disconnects I have to replug the keyboard back in for it to come back, headset and mouse go out for 5-10 seconds then come back. Happens quite frequently, at least once a minute (keyboard less often).

This is a near brand new PC and everything else works fine, including streaming with xsplit. OBS has been my streaming choice for a year or so now and has been working great up until the last few months where this started. Like I mentioned streaming with xsplit is great and causes 0 issues, which is what I have been forced to do.

Any help would be great, thanks.

That's technically not obs causing that; that's a hardware issue beyond obs' control. OBS cannot control any of your hardware in the way you describe, because it's just user space software, completely isolated from anything at the system level.

I'm going to pre-emptively assume you have a webcam as well, eating up USB/bus bandwidth and ultimately causing interference with other devices that your motherboard can't seem to handle for whatever reason (motherboards usually are able to handle this, I feel there is a serious defect in that motherboard if this is happening). RIght now, obs defaults to high webcam resolutions and higher bandwidth color spaces (which was a design flaw) rather than using lower values, so if you are using a webcam, go in to its properties, turn down resolution first and foremost, small as possible according to how much space it uses on screen. Then use MJPEG if it's available, otherwise whatever it defaults to. Then your issue should most likely be pretty much solved.

However if you do not have a webcam then I am not entirely sure, I can't see what would be causing the problem. You could try the multiplatform build to see if our optimizations there help, it also has better video device defaults, although it's still some time before it's ready to replace the original obs, because it still lacks many features.

Yes I am using a webcam and completely forgot to mention that, however what's puzzling to me is since this has started I have not changed any settings and everything on my end has been the same. Also if this is a hardware/bandwidth issue, why wouldn't the same issue replicate with xsplit. Does OBS encode differently that it uses more bandwidth?

Did you want me to change my webcam settings within OBS or should I install the webcam software

Also these are my PCs specs
