  55           Universal Serial Bus (USB) is a specification for a serial bus
  56           subsystem which offers higher speeds and more features than the
  57           traditional PC serial port.  The bus supplies power to peripherals
  58           and allows for hot swapping.  Up to 127 USB peripherals can be
  59           connected to a single USB host in a tree structure.
  60
  61           The USB host is the root of the tree, the peripherals are the
  62           leaves and the inner nodes are special USB devices called hubs.
  63           Most PCs now have USB host ports, used to connect peripherals
  64           such as scanners, keyboards, mice, modems, cameras, disks,
  65           flash memory, network links, and printers to the PC.
  66
  67           Say Y here if your computer has a host-side USB port and you want
  68           to use USB devices.  You then need to say Y to at least one of the
  69           Host Controller Driver (HCD) options below.  Choose a USB 1.1
  70           controller, such as "UHCI HCD support" or "OHCI HCD support",
  71           and "EHCI HCD (USB 2.0) support" except for older systems that
  72           do not have USB 2.0 support.  It doesn't normally hurt to select
  73           them all if you are not certain.
  74
  75           If your system has a device-side USB port, used in the peripheral
  76           side of the USB protocol, see the "USB Gadget" framework instead.
  77
  78           After choosing your HCD, then select drivers for the USB peripherals
  79           you'll be using.  You may want to check out the information provided
  80           in <file:Documentation/usb/> and especially the links given in
  81           <file:Documentation/usb/usb-help.txt>.

 106           This driver is for USB parallel port adapters that use the Lucent
 107           Technologies USS-720 chip. These cables are plugged into your USB
 108           port and provide USB compatibility to peripherals designed with
 109           parallel port interfaces.
 110
 111           The chip has two modes: automatic mode and manual mode. In automatic
 112           mode, it looks to the computer like a standard USB printer. Only
 113           printers may be connected to the USS-720 in this mode. The generic
 114           USB printer driver ("USB Printer support", above) may be used in
 115           that mode, and you can say N here if you want to use the chip only
 116           in this mode.
 117
 118           Manual mode is not limited to printers, any parallel port
 119           device should work. This driver utilizes manual mode.
 120           Note however that some operations are three orders of magnitude
 121           slower than on a PCI/ISA Parallel Port, so timing critical
 122           applications might not work.
 123
 124           Say Y here if you own an USS-720 USB->Parport cable and intend to
 125           connect anything other than a printer to it.
 126
 127           To compile this driver as a module, choose M here: the
 128           module will be called uss720.
