The bus supplies power to peripherals + and allows for hot swapping. Up to 127 USB peripherals can be + connected to a single USB host in a tree structure. + + The USB host is the root of the tree, the peripherals are the + leaves and the inner nodes are special USB devices called hubs. + Most PCs now have USB host ports, used to connect peripherals + such as scanners, keyboards, mice, modems, cameras, disks, + flash memory, network links, and printers to the PC. + + Say Y here if your computer has a host-side USB port and you want + to use USB devices. You then need to say Y to at least one of the + Host Controller Driver (HCD) options below. Choose a USB 1.1 + controller, such as "UHCI HCD support" or "OHCI HCD support", + and "EHCI HCD (USB 2.0) support" except for older systems that + do not have USB 2.0 support. It doesn't normally hurt to select + them all if you are not certain. + + If your system has a device-side USB port, used in the peripheral + side of the USB protocol, see the "USB Gadget" framework instead. + + After choosing your HCD, then select drivers for the USB peripherals + you'll be using.
