  59           Universal Serial Bus (USB) is a specification for a serial bus
  60           subsystem which offers higher speeds and more features than the
  61           traditional PC serial port.  The bus supplies power to peripherals
  62           and allows for hot swapping.  Up to 127 USB peripherals can be
  63           connected to a single USB host in a tree structure.
  64
  65           The USB host is the root of the tree, the peripherals are the
  66           leaves and the inner nodes are special USB devices called hubs.
  67           Most PCs now have USB host ports, used to connect peripherals
  68           such as scanners, keyboards, mice, modems, cameras, disks,
  69           flash memory, network links, and printers to the PC.
  70
  71           Say Y here if your computer has a host-side USB port and you want
  72           to use USB devices.  You then need to say Y to at least one of the
  73           Host Controller Driver (HCD) options below.  Choose a USB 1.1
  74           controller, such as "UHCI HCD support" or "OHCI HCD support",
  75           and "EHCI HCD (USB 2.0) support" except for older systems that
  76           do not have USB 2.0 support.  It doesn't normally hurt to select
  77           them all if you are not certain.
  78
  79           If your system has a device-side USB port, used in the peripheral
  80           side of the USB protocol, see the "USB Gadget" framework instead.
  81
  82           After choosing your HCD, then select drivers for the USB peripherals
  83           you'll be using.  You may want to check out the information provided
  84           in <file:Documentation/usb/> and especially the links given in
  85           <file:Documentation/usb/usb-help.txt>.
  86
  87           To compile this driver as a module, choose M here: the
  88           module will be called usbcore.

 110           This driver is for USB parallel port adapters that use the Lucent
 111           Technologies USS-720 chip. These cables are plugged into your USB
 112           port and provide USB compatibility to peripherals designed with
 113           parallel port interfaces.
 114
 115           The chip has two modes: automatic mode and manual mode. In automatic
 116           mode, it looks to the computer like a standard USB printer. Only
 117           printers may be connected to the USS-720 in this mode. The generic
 118           USB printer driver ("USB Printer support", above) may be used in
 119           that mode, and you can say N here if you want to use the chip only
 120           in this mode.
 121
 122           Manual mode is not limited to printers, any parallel port
 123           device should work. This driver utilizes manual mode.
 124           Note however that some operations are three orders of magnitude
 125           slower than on a PCI/ISA Parallel Port, so timing critical
 126           applications might not work.
 127
 128           Say Y here if you own an USS-720 USB->Parport cable and intend to
 129           connect anything other than a printer to it.
 130
 131           To compile this driver as a module, choose M here: the
 132           module will be called uss720.
