Input devices stop responding on Windows 11 PC
My keyboard, mouse, and external drives randomly freeze or disconnect on my Windows 11 PC, and they only come back after a reboot or unplugging them. This happens with USB and Bluetooth devices, even after updating drivers and checking power settings, so I need help figuring out the real cause.

USB and Bluetooth controllers are usually controlled by the motherboard chipset.
Because USB storage and Bluetooth input fail together, the symptoms do not identify one faulty peripheral. Keep USB selective suspend enabled; Microsoft recommends not disabling it. Disconnect hubs, connect only a wired keyboard and mouse directly, turn Bluetooth off, and test. Then disconnect USB accessories and test one re-paired Bluetooth device. This shows whether failure follows USB, Bluetooth, or the PC. Install all Windows updates and offered optional driver updates, then the latest chipset, USB, and Bluetooth drivers for your PC model from its manufacturer. Run the Windows Bluetooth troubleshooter and remove and add the affected device again. If the issue remains, perform a clean boot and try to reproduce it. If it disappears, re-enable startup items in groups. If both transports still fail during a clean boot, record the exact time and affected devices and contact the PC manufacturer. Restarting or reconnecting alone cannot establish the root cause.
