All USB devices Disconnect randomly on Windows 11.

Update, I went into device manager and selected every USB controller and device and went into settings and disable the “allow device to be powered down” option under the last power options tab and rebooted and I haven’t hit the disconnect or reconnect issue again after hours of use. I’m still not 100% sure if this solved the issue but it greatly improved things.

I also went into the BIOS and set all the USB stuff back to default. The network card also seems to be showing to reliably again too. I’ll update if I hit the issues again but this needs to be solved with a real fix so it doesn’t power down entire USB controllers and hubs to save power just bedause they haven’t done something for a little bit. Because the devices attached to them are still active like my keyboard and mouse for instance.

I'm getting this issue on a brand-new PC build and it's frustrating.

I thought it might be a lemon PSU, so I replaced it with a better one. It seems like it kind of helped, not getting daily crashes, but still getting the USB disconnects. I tried disabling the "allow device to be powered down" option on all USB devices and it did not help. System still did a full sweep disconnect of all USB devices with no option but to restart the PC. Also on 24H2.

at this point. those who are facing this issue shouldnt start changing things
its not anything we've changed', unless you changed something to make this happen.
in my case no..
so why should i change anything trying to chase a bug that i didnt cause.

So I am back yet again with some updates and answers.

Yes, I am running Windows 11 on both machines.

Sadly though I didn't check the forums before going back to the other PC so I didn't do the test, but both machines seem to run well yet again.

Main PC:

• I haven't had any disconnects since last I left an update, I updated to 24h2 today, so right now I have all the windows updates installed.
• I've changed my hub recently because of connection issues but that wasn't the reason the USB's would disconnect. [It happened even when the hub was disconnected from the front port]
• I'm using the PC without issues, I connect and disconnect external drives and the issue doesn't seem to reappear.

Alt PC:

• I've used it from December to mid-January.
• I've changed to different mouses, I haven't had a disconnection issue.
• I've had a lot of peripherals connected to that too and still no more USB issues.

At this moment, I at least, am back to square 1.

• I've checked voltages to make sure it's not a surcharge on the USB port(s) [fail-safe disconnections].
• I've checked USB event history and nothing seemed off before the disconnections happened.
• There are no same PC parts that we all use.
• There are no same third-party apps that we all use.
• There are no same external USB devices that we all use.

It's weird that for me at least, out of a sudden, everything is alright now for the last 4 months - 0 disconnects.

I think that the origin of this issue would be found in a closed environment with multiple PC's that have the same issue, cause right now the number of variables are a lot.

Sadly I don't think I'll be of any help since I've got nothing to diagnose anymore, but I'll keep an eye on the forum and if I can answer to any of your question or just in case I'll have any leads, information, etc., I'll write.

Good luck everyone!

This is already my 2nd Windows 11 laptop that does this. I have a Yenkee Spark speaker connected through USB cable and just a minute or two later it suddently gets disconnected and goes into a bluetooth mode. It happened to me on an Asus and Lenovo laptops but for some reason not on Acer (all have Win 11). This is just terrible incompetence on MS side.
