Fix USB Devices

Fix USB Devices repairs the Windows USB subsystem to resolve detection, connection, and power delivery issues. It disables USB Selective Suspend (the #1 cause of random disconnects), resets USB Root Hub power management settings, reinstalls USB host controller drivers, clears cached USB device descriptors, and re-enumerates all connected devices. It handles both USB 2.0 and USB 3.0/3.1/3.2 ports, and works with drives, keyboards, mice, printers, and other USB peripherals. Takes about 2 minutes with no restart needed in most cases.
