Every USB version, including USB 3.0, USB 2.0, and USB 1.1, supports B type . The Powered-B connector is a second type of “B” connector that is only available in USB 3.0.

Larger computer devices, such as printers and scanners, are the most popular B type receptacles. External storage devices such as optical discs, floppy drives, and hard drive enclosures may also have USB Type-B

A USB A/B usually has a B-type header plug on one end. The USB Type-B plug is inserted into the B type header receptacle on the printer or other device, whereas the USB Type-A plug is inserted into the USB Type-A receptacle on the host device, such as a computer.

Compatibility with USB Type-B

Because the B type usb header in USB 2.0 and USB 1.1 are identical, the USB Type B plug from one USB version will fit into the USB Type-B receptacle from the other USB version.

Because the USB 3.0 Type B usb header are different in design from earlier ones, the plugs will not fit into earlier receptacles. The new USB 3.0 Type B form factor, on the other hand, was created in such a way that existing USB Type-B plugs from USB 2.0 and USB 1.1 can be used in USB 3.0 Type B receptacles.

In other words, USB 1.1 and 2.0 Type B plugs work with USB 3.0 Type B receptacles physically, while USB 3.0 Type B plugs do not work with USB 1.1 or 2.0 Type B receptacles.

The reason for the change is because the USB 3.0 B type usb header features nine pins instead of the four seen in the prior B type allowing for greater data transfer rates. Because the pins needed to go somewhere, the Type B shape had to be changed slightly.

USB 3.0 Standard-B and USB 3.0 Powered-B are the two USB 3.0 Type B connections. The plugs and receptacles have the same design and adhere to the same physical compatibility standards, however, the USB 3.0 Powered-B USB header contains two additional power pins, for a total of eleven pins.
