I installed Windows 10 earlier this week. All week my computer has functioned fine, but today when I turned it on I get an alert saying USB Device not recognized. I have several USB devices plugged into a StarTech (SV231) KVM switch and then one USB from that to my computer.
The KVM switch worked all week and without intentionally installing anything or doing anything out of the ordinary, suddenly, today I'm not able to plug any USBs into the KVM switch.
Plugging the keyboard and mouse directly into the computer works, but plugging them into the KVM gives me the "USB Device not recognized" alert.
I looked for some sort of driver software for the KVM but there doesn't seem to be any available and I'm not sure what else to do.

The problem was solved by powering off the KVM switch and powering it back on.
Note that unplugging the power cable does not completely power off the KVM switch as any USB cable connected to the switch while also connected to PC will also provide power to the switch.
You should remove all USB cables connecting the KVM to a power source and remove the power source.
