When this device appears as an "Unknown Device," it typically points to configuration gaps between the host system and the virtual machine.
Note: Modern Windows operating systems handle this automatically via Windows Update, but manual installation is required on older server distributions. 2. Trigger Windows Update Within the Guest OS
