34 You will also need drivers from the following menu to make use of it.

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

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

182 LEDs and you want to use them as activity indicators for USB host or
186 tristate "USB ULPI PHY interface support"
189 UTMI+ Low Pin Interface (ULPI) is specification for a commonly used
190 USB 2.0 PHY interface. The ULPI specification defines a standard set
191 of registers that can be used to detect the vendor and product which
192 allows ULPI to be handled as a bus. This module is the driver for that
195 The ULPI interfaces (the buses) are registered by the drivers for USB
196 controllers which support ULPI register access and have ULPI PHY
197 attached to them. The ULPI PHY drivers themselves are normal PHY
200 ULPI PHYs provide often functions such as ADP sensing/probing (OTG
201 protocol) and USB charger detection.
