Types a and b have 4 pins within the connector mini and micro a and b connectors generally have five pins.

Usb cable power pins.

Pinout of usb and layout of 4 pin usb a or usb b plug connector and 4 pin usb a usb b mini usb jack connectorusb universal serial bus designed to connect peripherals such as mice keyboards scanners digital cameras printers hard disks and networking components to pc. Besides some active cables utilize a re driver chip to strengthen the signal and compensate for the losses incurred by the cable etc. Two for power 5v gnd and two for differential data signals labelled as d and d in pinout. As a result there are many usb connector types.
