Windows 11 shows Code 19 and none of my USB mice work
Asked by

After shutting down my Windows 11 PC normally, I turned it on the next day and discovered that my Logitech mouse no longer worked. I tried plugging in three different mice, but none were detected or usable. Using only the keyboard, I opened Device Manager, uninstalled the mouse devices, and restarted the computer, but the problem remained. Device Manager reports Code 19 for the mouse. What should I try next?
Answers
Code 19 usually means Windows has damaged or incomplete registry information for that device. In Device Manager, open the mouse properties and check the exact error under the General tab. Try uninstalling the affected mouse and any related USB or HID entries, then restart so Windows can detect them again. If that does not help, install the latest chipset and USB drivers from your computer or motherboard manufacturer.

Since multiple mice fail, the problem may be with the USB controller rather than the Logitech mouse itself. Test the mice in different USB ports, including both front and rear ports, and check whether a USB keyboard or flash drive works. Also look in Device Manager under Universal Serial Bus controllers for devices with warning icons. A recent Windows update or driver change could have disabled the controller, so rolling back or reinstalling the USB controller driver may help.

MellowKite42: I am not sure whether an update disabled the USB ports. I will check the USB controller entries and try the other ports.
