All USB devices Disconnect randomly on Windows 11.

Ha ha..! Thanks for doing that, it helps a lot. I think with my own experimenting it does sound like we might have a possible workaround - Disable Edge from Startup!

Not wishing to count my chickens but this probably does need a little more input from the community before we can say it's an absolute but at least you and I both now have a verifiable workaround for now. Sounds like you might need to install a different browser after all, either that or see what happens with Edge set to launch manually when you need it.

Hopefully others can add some feedback here for good measure.

yea no problem! it was incredibly boring but worth it! Maybe chrome, opera, duckduckgo or mozilla would work. Ill test that out though!

Good! great it's working again! I've been playing for the past 4 hours and only have had 2 disconnects!

Just for interest, although everything is working as it should be this end (never thought I would say that again), I just plugged one of my USB thumb drives into my front USB port and for some reason it wouldn't let me use 'SHIFT-DELETE' to permanently delete a file, it felt like some background process was preventing this (call it a hunch). Anyway, a quick look in Task Manager revealed that Microsoft Edge was running and was consuming over 300 mb's of memory. I don't use Edge unless I need to so I ended the task and I was immediately able to permanently delete my files.

Who'd have thought that a web browser could impact on USB functionality! Something someone else mentioned here previously.

hmmmm, I don't use chrome, as i never installed it lol, now that i think of it, my disconnects mainly happen when edge is open! Ill run my pc for a few hours today and just record on a camera or something while edge is open then a few hours while its not! ill let you guys know what happens!

I'm not into criticizing other folks systems, we buy what we can afford or what we actually need. You always get the flash Harry's who have to buy the next big thing but I'm a bit more sensible with my money.

My PC is about my fourth self-build now, an ASUS Prime B350 Plus Motherboard - Ryzen 5 - 1600 3.20 MHz Processor - 16 Gigs DDR4 RAM - NVIDIA GeForce GTX 1050Ti Graphics. I/O Plate on rear of PC supports: 2 x USB 2.0, 4 x USB 3.0 & 2 x USB 3.1

I'm a graphics designer so don't need anything faster, I can still render huge image files, sometimes several Gb's with no problems.

Interestingly, since my earlier post today it got me thinking, I've experimented using the USB 2.0 sockets on the I/O plate and discovered they're not affected so I've just tried the USB 3.0 & 3.1 sockets, all of which now seem to be working without issue, how strange!! This has obviously corrected itself without me noticing.

This just leaves the 2 x USB 3.0 sockets on my front facing hub, until recently I used them regularly for charging my phone or transferring data to or from a thumb drive but since this issue reared it's ugly head, I've been using the USB sockets on my monitor instead. So to rule out a dodgy socket I just tried plugging my phone into each one to see if these are now working and much to my surprise one of them is, it's the one on the left which I tend to use less often than the one on the right. Annoyingly however the right one is producing the disconnect fault. I guess this is a bit of a 'Eureka' moment for me, something tells me that my hub might well be faulty, NOT Windows 11.

Don't get me wrong.., I was experiencing the disconnect issues with the rear facing USB sockets on the I/O plate previously, but not any longer. Perhaps the issue has been fixed without me knowing and the issue with the dodgy socket on the front hub was just a red herring?

I suppose if anyone can take anything from my experience, it would be to check all of your USB sockets one by one and see what you discover. Sure., it's a bit of hassle disconnecting everything, I'm lazy and rarely bother experimenting, but I'm sure as hell glad I did today!
