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

  86         help
  87           Many embedded system SOCs (e.g. freescale T2080) have both
  88           PCI and USB modules with the USB module directly controlled by
  89           registers and having no relationship to the PCI module.
  90
  91           If you have such a device you may say N here and PCI related code
  92           will not be built in the USB driver.

 137           This driver is for USB parallel port adapters that use the Lucent
 138           Technologies USS-720 chip. These cables are plugged into your USB
 139           port and provide USB compatibility to peripherals designed with
 140           parallel port interfaces.
 141
 142           The chip has two modes: automatic mode and manual mode. In automatic
 143           mode, it looks to the computer like a standard USB printer. Only
 144           printers may be connected to the USS-720 in this mode. The generic
 145           USB printer driver ("USB Printer support", above) may be used in
 146           that mode, and you can say N here if you want to use the chip only
 147           in this mode.
 148
 149           Manual mode is not limited to printers, any parallel port
 150           device should work. This driver utilizes manual mode.
 151           Note however that some operations are three orders of magnitude
 152           slower than on a PCI/ISA Parallel Port, so timing critical
 153           applications might not work.
 154
 155           Say Y here if you own an USS-720 USB->Parport cable and intend to
 156           connect anything other than a printer to it.
 157
 158           To compile this driver as a module, choose M here: the
 159           module will be called uss720.
