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

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

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

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