27 This option adds core support for Universal Serial Bus (USB).
28 You will also need drivers from the following menu to make use of it.

42 select NLS # for UTF-8 strings
44 Universal Serial Bus (USB) is a specification for a serial bus
45 subsystem which offers higher speeds and more features than the
46 traditional PC serial port. The bus supplies power to peripherals
47 and allows for hot swapping. Up to 127 USB peripherals can be
48 connected to a single USB host in a tree structure.
50 The USB host is the root of the tree, the peripherals are the
51 leaves and the inner nodes are special USB devices called hubs.
52 Most PCs now have USB host ports, used to connect peripherals
53 such as scanners, keyboards, mice, modems, cameras, disks,
54 flash memory, network links, and printers to the PC.
56 Say Y here if your computer has a host-side USB port and you want
57 to use USB devices. You then need to say Y to at least one of the
58 Host Controller Driver (HCD) options below. Choose a USB 1.1
59 controller, such as "UHCI HCD support" or "OHCI HCD support",
60 and "EHCI HCD (USB 2.0) support" except for older systems that
61 do not have USB 2.0 support. It doesn't normally hurt to select
62 them all if you are not certain.
64 If your system has a device-side USB port, used in the peripheral
65 side of the USB protocol, see the "USB Gadget" framework instead.
67 After choosing your HCD, then select drivers for the USB peripherals
68 you'll be using. You may want to check out the information provided
69 in <file:Documentation/usb/> and especially the links given in
70 <file:Documentation/usb/usb-help.txt>.
72 To compile this driver as a module, choose M here: the
73 module will be called usbcore.
76 bool "PCI based USB host interface"
80 Many embedded system SOCs (e.g. freescale T2080) have both
81 PCI and USB modules with the USB module directly controlled by
82 registers and having no relationship to the PCI module.
84 If you have such a device you may say N here and PCI related code
85 will not be built in the USB driver.

126 tristate "USS720 parport driver"
128 select PARPORT_NOT_PC
130 This driver is for USB parallel port adapters that use the Lucent
131 Technologies USS-720 chip. These cables are plugged into your USB
132 port and provide USB compatibility to peripherals designed with
133 parallel port interfaces.
135 The chip has two modes: automatic mode and manual mode. In automatic
136 mode, it looks to the computer like a standard USB printer. Only
137 printers may be connected to the USS-720 in this mode. The generic
138 USB printer driver ("USB Printer support", above) may be used in
139 that mode, and you can say N here if you want to use the chip only
142 Manual mode is not limited to printers, any parallel port
143 device should work. This driver utilizes manual mode.
144 Note however that some operations are three orders of magnitude
145 slower than on a PCI/ISA Parallel Port, so timing critical
146 applications might not work.
148 Say Y here if you own an USS-720 USB->Parport cable and intend to
149 connect anything other than a printer to it.
151 To compile this driver as a module, choose M here: the
152 module will be called uss720.

173 This option adds LED triggers for USB host and/or gadget activity.
175 Say Y here if you are working on a system with led-class supported
176 LEDs and you want to use them as activity indicators for USB host or
180 tristate "USB ULPI PHY interface support"
183 UTMI+ Low Pin Interface (ULPI) is specification for a commonly used
184 USB 2.0 PHY interface. The ULPI specification defines a standard set
185 of registers that can be used to detect the vendor and product which
186 allows ULPI to be handled as a bus. This module is the driver for that
189 The ULPI interfaces (the buses) are registered by the drivers for USB
190 controllers which support ULPI register access and have ULPI PHY
191 attached to them. The ULPI PHY drivers themselves are normal PHY
194 ULPI PHYs provide often functions such as ADP sensing/probing (OTG
195 protocol) and USB charger detection.
