USB 2.0 is a Universal Serial Bus (USB) standard. Almost all devices with USB capabilities, and nearly all USB cables, support at least USB 2.0.
Devices that adhere to the USB 2.0 standard have the ability to transmit data at a maximum speed of 480 Mbps. This is faster than the older USB 1.1standard and much slower than the newer USB 3.0 standard.
USB 1.1 was released in August 1998, USB 2.0 in April 2000, and USB 3.0 in November 2008.
Older USB 1.1 devices and cables are, for the most part, physically compatible with USB 2.0 hardware. However, the only way to reach USB 2.0 transmission speeds is if all devices and cables being connected to each other support USB 2.0.
If, for example, you have a USB 2.0 device used with a USB 1.0 cable, the 1.0 speed will be used regardless of the fact that the device supports USB 2.0 since that cable does not support the newer, faster speeds.
USB 2.0 devices and cables used with USB 3.0 devices and cables, assuming they're physically compatible, will operate at the lower USB 2.0 speed.
In other words, the transmission speed falls to the older of the two technologies. This makes sense since you can't pull USB 3.0 speeds out of a USB 2.0 cable, nor can you get USB 2.0 transmission speeds using a USB 1.1 cable.
FAQ
● What Is USB 3.0?
USB 3.0 was released in November 2008, which is the third major version of the Universal Serial Bus standard for interfacing computers and electronic devices. USB 3.0 has gradually become the new standard for USB devices by providing a lot of improvements over USB 2.0.
● Is USB 3.0 the same as USB C?
The primary distinction between USB C and USB 3 is that one is a type of USB connector, while the other is a speed standard for USB cables in general. Some devices use it instead of older USB-A connectors or micro USB ports. Conversely, USB 3 is a standard for USB devices.
