What is PCI Simple Communications Controller or PCI Serial Port?

PCI stands for Peripheral Component Interconnect, which is a standard for connecting devices to the motherboard of a computer. PCI devices can include sound cards, network cards, modems, and other components. A PCI Simple Communications Controller is a generic name for a device that performs basic communication functions, such as modems or network adapters. A PCI Serial Port is a specific type of PCI device that uses a serial interface to communicate with other devices, such as printers or scanners.

Why does the error occur?

The error on PCI Simple Communications Controller or PCI Serial Port in Device Manager occurs when the driver for the device is missing or outdated. The driver is a software program that allows the operating system to communicate with the hardware device. Without the driver, the device cannot function properly and may cause conflicts with other devices. The error may also display a code or an ID that identifies the device and its manufacturer.
