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

  69. Many embedded system SOCs (e.g. freescale T2080) have both
  70. PCI and USB modules with the USB module directly controlled by
  71. registers and having no relationship to the PCI module.
  72. If you have such a device you may say N here and PCI related code
  73. will not be built in the USB driver.

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