Possible, so that only one remains connected to the affected hub, to see which one triggers the events.Īgain, in this particular example, even touching the keyboard connection triggered several events. If you happen to have more than one device plugged into the same hub, try to use other available ports, if To actually disconnect and reconnect the keyboard to see if we can capture the event again, and if it matches. Indeed, I happen to have the desktop keyboard connected to the particular four-port panel. Which means this is where we ought to look. Ports on a panel, normally at the back of your computer case. This means that you can normally expect to see four available USB In my case, it happens to be a Generic USB Hub, and with the following Check the properties of every USB controller until you find Open the Device Manager (My Computer > Manage).

In this case, it was a generic USB hub, port 2, hub 3 what dunnit it. What do we have here? Within one second, we had the unplug-plug sequence, hence the sounds. And indeed, it captured an event, reading thusly: Like that sentence in Braveheart, yes, you can run for a On my affected host, I let USBLogView run for a while. Once we have this, weĬan start figuring out what kind of an issue we're dealing with, if any. While running, will capture all USB events and log them. There is an extremely nifty tool called USBLogView, developed by legendary Nir Sofer. That there's no quick correlation between sounds and functionality, so we need to do some forensics. This could be happeningĮvery few minutes or maybe once an hour or every other day.
Something USB seems to be disconnecting and reconnecting. But if you're wondering if your Windows has gone mental, the answer is, The solution will often be quiteĮasy once you know where to look. Let me show you how you should go about troubleshooting an issue like this.
