Why is the USB to Serial Adapter Cable used?

The USB to Serial Adapter Cable is particularly valuable in environments where connections to devices require a serial interface instead of or in addition to USB. This adapter is widely used to establish console connections to network devices such as LSC (Local Session Controller) and Ethernet switches. These devices typically operate with serial communication protocols for configuration and management purposes, which makes the USB to Serial Adapter essential.

In context, other answers might touch on valid uses for USB connections or data transfer; however, they do not align as closely with the primary function of the USB to Serial Adapter specifically in networking or console access scenarios. Thus, the use of such an adapter to facilitate communication with devices that rely on serial ports clarifies why the option focusing on console connectivity is the most relevant answer.
