Robust connections for larger peripheral devices
USB Type-B connectors, typically called USB-B connectors, are a kind of Universal Serial Bus (USB) device. These have squarish or thin rectangular shapes with slightly beveled corners on the top ends. Standard USB-B connectors are commonly used on larger peripheral devices that connect to a host computer, remain stationary, and do not require frequent unplugging, such as printers, scanners, and external hard drives. The USB-B connector on a peripheral device is commonly paired with a USB-A or USB-C connector on the host device. USB-B connectors support USB 2.0 speeds (up to 480 Mbps), and in some cases USB 3.0 speeds (up to 5 Gbps).
Other versions of USB-B connectors have been created over the years, including the smaller form factor Mini USB-B, Micro USB-B, and USB 3.0 Micro-B connectors. The USB 3.0 Micro-B connector is designed for higher data transfer speeds and is commonly used to connect external hard drives and other high-speed peripherals to computers. USB 3.0 Micro-B is backward compatible with USB 2.0 but has more pins and a secondary connector extension for USB 3.0 data transfer.
