Are USB 3 and USB 2 connectors the same?
These connector types are larger than the 2.0 equivalents and are not compatible with 2.0 ports. USB 3.0 cables also have the additional power transfer of 900 mA as opposed to USB 2.0 cables, which provide power up to 500 mA. One of the rare areas in which USB 2.0 cables actually beat out the 3s is in cord length.
