— presence of at least one USB 2.0 connector on the back of the controller.USB (all versions) is the most popular modern interface for connecting external peripherals. Specifically, the USB 2.0 standard is now considered obsolete: for example, the data transfer rate with such a connection does not exceed 480 Mbps, and the power supply is very low. And although such capabilities are quite sufficient at least for undemanding peripherals like keyboards, mice, etc., however, PCI controllers with this type of connector are becoming less common — manufacturers generally prefer more advanced interfaces, such as USB 3.2 gen1 and gen2 ( see relevant paragraphs).
