Conclusion The PCI Simple Communications Controller is a catch-all label for unrecognized communication-class PCI devices. On virtually all modern Intel-based systems, it represents the interface to the Intel Management Engine. While it is not required for basic computer operation, installing the correct driver is necessary for full platform features and to clear the warning in Device Manager. For security-conscious users who do not use Intel AMT, leaving the device disabled or uninstalled is a valid, safe practice. lspci -nn | grep -i communication Output example:
