Universal Serial Bus (USB) is a specification to establish communication between devices and a host controller (usually personal computer).
Bus-powered hubs can continue to distribute the bus provided power to connected devices but the USB specification only allows for a single level of bus-powered devices from a bus-powered hub.
This address is used to detect the particular USB device.
Due to the ability to supply power to the preipheral devices USB is often used as a power charger for portable devices.I recommend you to use a hub with an external power supply if you want to connect more than 2 or 3 devices because they will absorb a large amount of current and the USB port cannot provide it by itself.Devices that need more than 500 mA or higher than 5 volts must provide their own power.The other end of the cable has series B connector which is used to plug into the B type receptacle.The USB standard supports the data transfer at the rate of 12 Mbps.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.
The USB host controllers has their own specifications: uhci (Universal Host Controller Interface ohci (Open Host Controller Interface) with USB.1, ehci (Enhanced Host Controller Interface) is used with USB.0.
Mini-USB pinout and, micro-USB pinout are slightly different: standard USB uses 4 pins while Mini-USB and Micro-USB uses 5 pins in connector.
