Which version of USB has a transfer rate of 480 mbps?

The version of USB that has a transfer rate of 480 Mbps is USB 2.0. This version was a significant improvement over its predecessor, USB 1.1, which had much lower speeds (1.5 Mbps for low-speed devices and 12 Mbps for full-speed devices).

USB 2.0 introduced a new standard for enhanced data transfer rates, enabling devices to communicate faster and more efficiently. The 480 Mbps speed facilitated better performance and supported a wider range of devices, such as external hard drives and high-speed peripherals.

In contrast, USB 3.0 significantly increased the transfer rate to 5 Gbps, and USB 4.0 continues this trend with even higher speeds. Therefore, while USB 2.0 is known for its 480 Mbps transfer rate, the later versions have introduced much faster speeds, making it clear why USB 2.0 is the correct answer for the specified transfer rate in the question.
