The different A and B plugs prevent accidentally connecting two power sources. USB cables and small USB devices are held in place by the gripping force from the receptacle, with no screws, clips, or thumb-turns as other connectors use. The USB specification requires that the cable plug and receptacle be marked so the user can recognize the proper orientation. Д«y design, it is difficult to insert a USB plug into its receptacle incorrectly. The official USB specification documents also periodically define the term male to represent the plug, and female to represent the receptacle. The female connector mounted on the host or device is called the receptacle, and the male connector attached to the cable is called the plug. The connectors the USB committee specifies support a number of USB's underlying goals, and reflect lessons learned from the many connectors the computer industry has used. USB extension cable, male plug on the left, female socket on the right The mini and micro formats may connect to an AB receptacle, which accepts either an A or a B plug. USB cables typically have male plugs on each end, and the corresponding receptacle is usually on a computer or electronic device. Each format has a plug and receptacle defined for each of the A and B ends. Thus, USB cables have different ends: A and B, with different physical connectors for each. Only downstream facing ports provide power this topology was chosen to easily prevent electrical overloads and damaged equipment. Unlike other data buses (such as Ethernet), USB connections are directed a host device has 'downstream' facing ports that connect to the 'upstream' facing ports of devices.

Modes are identified by their names and icons, and the specification suggests that plugs and receptacles be colour-coded (SuperSpeed is identified by blue). USB devices have some choice of implemented modes, and USB version is not a reliable statement of implemented modes. The modes have differing hardware and cabling requirements.

There are five speeds for USB data transfer: Low Speed, Full Speed, High Speed (from version 2.0 of the specification), SuperSpeed (from version 3.0), and SuperSpeed+ (from version 3.1).

The three sizes of USB connectors are the default or standard format intended for desktop or portable equipment, the mini intended for mobile equipment, and the thinner micro size, for low-profile mobile equipment such as mobile phones and tablets. USB has been selected as the standard charging format for many mobile phones, reducing the proliferation of proprietary chargers.Д¬omparison of USB connector plugs, excluding USB-C type plugs The USB standard included power supply to peripheral devices modern versions of the standard extend the power delivery limits for battery charging and devices requiring up to 100 watts. All versions of USB specify cable properties version 3.X cables include additional data paths. Higher-speed development of the USB standard gave rise to another family of connectors to permit additional data paths. The initial versions of the USB standard specified connectors that were easy to use and that would have acceptable life spans revisions of the standard added smaller connectors useful for compact portable devices.
