The PL2303 driver, the Prolific driver, is used to connect devices and Windows PCs using a USB-to-serial cable. Serial ports are used to connect various types of devices to computers, including industrial equipment, sensors, telescopes, GPS units, and more.
However, Windows 11 requires specific drivers to recognize and connect the two devices. The operating system downloads specific drivers from Microsoft servers when you connect your computer with such devices without ready drivers.
Sometimes, a specific driver is not available on Microsoft servers, or the Windows settings you configured cannot download drivers for the device you are connecting to. In this case, you need to download the driver from its official website.
However, it is easy to install the PL2303 driver on Windows 11 and doesn’t need much time.
