Weird things are happening to my rig today: Things were working fine this morning, then when the machine was rebooted earlier the cursor failed to appear, and the keyboard was unresponsive. As you can see from the image above, device manager is missing the mouse/keyboard groups, and the system can see no hardware installed. However, the HID and USB input devices are detected (and dynamically disappear when the mouse/kb are detached and reattached). The printers and devices box can also see them and the properties in there. Things I've tried: Booting into UEFI, where both devices function perfectly. Removing devices from Printers and devices, then rebooting and allowing them to reinstall. Removing all components from device manager under the Human Iput Devices, rebooting to allow reinstall. Nope. Plugging in an alternative keyboard, it's detected, but there's no response. Unplugging all other USB devices and trying each device individually. Trying alternative USB ports, they are detected in each case but give no input. I'm controlling the rig from Teamviewer at the moment with no issue. All other USB devices are working as normal. No updated were installed or changes made prior to the devices ceasing to function. AV scans show nothing untoward. Help!
