2.1.5 USB Cables and Standards

This section covers USB cable types and connector matching. The core skill is knowing which connector type goes with which device.

USB Hub and Device Connections

Hub to Computer

• The USB hub uses a 5-pin Mini USB (Mini-B) port on its back.
• Cable used: Mini-B connector into the hub, then Type-A connector into the computer.

Hub Front Ports

• The hub has 4 USB-A ports on the front for connecting peripherals.

Printers and Scanner

• All three use a standard USB-B connector, the larger square-shaped one.
• USB-B is standard for most large printers and scanners.

Portable External Hard Drive

• Uses a 5-pin Mini USB (Mini-B) connector, the same type as the hub.
• The other end plugs into the computer as Type-A.
