A USB male to male cable 2.0 is a cable with USB Type-A male connectors on both ends. These cables are designed to connect two USB Type-A ports, typically found on computers, hubs, or other USB devices. The "2.0" designation indicates that the cable follows the USB 2.0 specification, which supports data transfer rates of up to 480 megabits per second (Mbps).

It's essential to note that male-to-male USB cables are not as common as other USB cable types because connecting two host devices directly can cause issues and is generally not recommended. However, they can be used in specific scenarios, such as connecting two computers for data transfer or connecting certain specialized devices. Always ensure you're using cables appropriately to avoid damaging devices or causing data loss.
