Most USB Type B connectors are at one end of a USB Type B to USB Type A cable. You plug the Type-B connector into the printer, scanner or other device and the Type A connector into the standard USB port on your computer. DOES MY LAPTOP HAVE USB TYPE C? The standard connectors were designed to be more robust than many past connectors. This is because USB is hot-swappable, and the connectors would be used more frequently, and perhaps with less care, than previous connectors. The USB 3.0 cable connects to the camera using a Micro-B connector to ensure delivery of excellent performance. a b Universal Serial Bus 3.0 Specification: Revision 1.0. June 6, 2011. p.531.

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. Higher-speed development of the USB standard gave rise to another family of connectors to permit additional data paths. All versions of USB specify cable properties; version 3. x cables include additional data paths. 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 240 watts. USB has been selected as the standard charging format for many mobile phones, reducing the proliferation of proprietary chargers. In every instance, when dealing with power and electronic devices, power matters. This includes USB standards, and it is evident by the increase in functionality as the standards evolved. For example, with USB 1.1, it was functionally compatible with keyboards, mice, and printers as a connection option. However, with USB 2.0, it afforded the use of flash drives and other external hard drives. Battery Charging v1.2 Spec and Adopters Agreement" (Zip). USB Implementers Forum. March 15, 2012.

Since USB 3.1 can output 3 A, the device’s software will negotiate its requirements to limit the output to 2.1 A. Scenarios such as this are due to a device’s irregular or nonstandard power requirements.

With these cables, the type is whichever end of the cable isn’t the standard USB Type-A connector. So, for example, a cable with both a USB Type-A and a Type-C connector is a USB Type-C cable. The D± signals used by low, full, and high speed are carried over a twisted pair (typically unshielded) to reduce noise and crosstalk. SuperSpeed uses separate transmit and receive differential pairs, which additionally require shielding (typically, shielded twisted pair but twinax is also mentioned by the specification). Thus, to support SuperSpeed data transmission, cables contain twice as many wires and are larger in diameter. [34] How was it any different than USB-A? USB-A had 1.1, 2.0, 3.0, 3.2. There wasn't a cable issue with 1.1 or 2.0, but 3 and 3.2 it started to matter. Revision 1.2 of the specification was released in 2010. It made several changes, and increased limits including allowing 1.5A on charging downstream ports for unconfigured devices—allowing High Speed communication while having a current up to 1.5A. Also, support was removed for charging port detection via resistive mechanisms. [52] The USB Power Delivery specification revision2.0 (USB PD Rev. 2.0) has been released as part of the USB3.1 suite. [56] [64] [65] It covers the USB-C cable and connector with a separate configuration channel, which now hosts a DC coupled low-frequency BMC-coded data channel that reduces the possibilities for RF interference. [66] Power Delivery protocols have been updated to facilitate USB-C features such as cable ID function, Alternate Mode negotiation, increased V BUS currents, and V CONN-powered accessories.

Constructed to the Highest USB Specifications

USB cables come in different shapes and designs. Therefore, based on their physical structure, they are classified as follows:

USB-B is primarily used with the largest peripherals, such as printers. It can also be found on USB hubs or monitors that have USB hubs built into them, though the B port is always part of the wire that connects that hub/monitor to your PC. Mini USB Some cables have the same connector at both ends and are named accordingly—for example, a USB Type-C to USB Type-C cable.
