| 4 | Universal Serial Bus (USB) is a specification for a serial bus |
| 5 | subsystem which offers higher speeds and more features than the |
| 6 | traditional PC serial port. The bus supplies power to peripherals |
| 7 | and allows for hot swapping. Up to 127 USB peripherals can be |
| 8 | connected to a single USB host in a tree structure. |
| 9 | |
| 10 | The USB host is the root of the tree, the peripherals are the |
| 11 | leaves and the inner nodes are special USB devices called hubs. |
| 12 | Most PCs now have USB host ports, used to connect peripherals |
| 13 | such as scanners, keyboards, mice, modems, cameras, disks, |
| 14 | flash memory, network links, and printers to the PC. |

| 23 | do not have USB 2.0 support. It doesn't normally hurt to select |
| 24 | them all if you are not certain. |

| 26 | If your system has a device-side USB port, used in the peripheral |
