You may notice USB devices may stop functioning correctly when multiple devices connected to the same USB hub go into selective suspend. In this post, we will identify the root cause of the issue, as well as provide the most suitable solutions to resolve the issue on your Windows 11 or Windows 10 computer.
When this issue occurs, you’ll notice USB devices attached to the same hub are very slow or completely unresponsive. This issue occurs when one of the devices on the hub receives a wake request while the other devices that are attached to the same hub are going into selective suspend. If this happens before the suspend request has completed, the devices become unstable.

Why do USB hubs stop working?
USB hubs can stop working due to static electricity which causes ports in the hub to stop working. A quick fix to this issue is to disconnect the power plug and the plug connecting the hub to the USB port on your computer, wait a few seconds and then reconnect the USB hub back to the system.
Why does a USB hub need to be powered?
There are 3 common hub types viz; Root hub, Powered hub and Self-powered hub. A powered hub uses mains power, it can supply every device connected to it the maximum voltage that USB allows. So, not only can it run more devices than an unpowered hub, it can do so at full power, without any performance hits.
That’s it!
