43	---help---
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.
49
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.
55
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.
63
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.
66
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>.
71
72	  To compile this driver as a module, choose M here: the
73	  module will be called usbcore.
74
75config USB_PCI
76	bool "PCI based USB host interface"
77	depends on PCI
78	default y
79	---help---
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.
83
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.

129	---help---
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.
134
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
140	  in this mode.
141
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.
147
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.
150
151	  To compile this driver as a module, choose M here: the
152	  module will be called uss720.

182	help
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
187	  bus.
188
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
192	  drivers.
193
194	  ULPI PHYs provide often functions such as ADP sensing/probing (OTG
195	  protocol) and USB charger detection.
196
197	  To compile this driver as a module, choose M here: the module will
198	  be called ulpi.
