USB supports four data rates: A USB device must indicate its speed by pulling either the D or D- line high to 3.3 volts.These pull up resistors at the device end will also be used by the host or hub to detect the presence of a device connected to its port.A USB 3.0 Standard-A receptacle accepts either a USB 3.0 Standard-A plug or a USB 2.0 Standard-A plug.

They are superseeded by the Micro-USB connector and it's successor USB type-C.

USB is a serial bus (usb pinout and signals wiring diagram).

However, it is not possible to plug a USB 3.0 Standard-B plug into a USB 2.0 Standard-B receptacle, due to a physically larger connector. Since USB 2.0 and USB 3.0 ports may coexist on the same machine and they look similar, USB 3.0 specification mandates appropriate color-coding and recommends that the Standard-A USB 3.0 connector has a blue insert.

The same color-coding applies to the USB 3.0 Standard-A plug.

The interface is suitable for one-of-kind and small-scale designs as well as mass-produced, standard peripheral types.

USB 3.0 connectors are usually distinguished from their USB 2.0 counterparts by blue color-coding of the receptacles and plugs.

USB 3.0 connectors are usually distinguished from their USB 2.0 counterparts by blue color-coding of the receptacles and plugs, and the initials SS.

A successor standard, USB 3.1 (USB 3.1 Gen 2), was released in July 2013 with the new transfer mode Super Speed that can transfer data at up to 10 Gbit/s (1.25 GB/s, twice the rate of USB 3.0), bringing its theoretical maximum speed on par with the first version of the Thunderbolt interface.

USB 3.0 is the third major version of the Universal Serial Bus (USB) standard for interfacing computers and electronic devices.

USB 3.0 combines USB 2.0 bus and new Super Speed bus with transfer rate up to 5.0 Gbit/s, which is about ten times faster than the USB 2.0 standard.

    The number of pins on each end can also be an identifier, by having more pins than your standard 2.0 cables. The preferred maximum length of a USB 3.0 cable is at 3 meters or 9.8 feet. This is to avoid data transmitted to cause data loss and corruption. You can grab a USB 3.0 cable with A-Male and B-Male plugs at 3 feet for around $9.00.…
