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	  A lot of embeded system SOC (e.g. freescale T2080) have both
81	  PCI and USB modules. But USB module is controlled by registers
82	  directly, it have no relationship with PCI module.
83
84	  When say N here it will not build PCI related code in USB driver.

128	---help---
129	  This driver is for USB parallel port adapters that use the Lucent
130	  Technologies USS-720 chip. These cables are plugged into your USB
131	  port and provide USB compatibility to peripherals designed with
132	  parallel port interfaces.
133
134	  The chip has two modes: automatic mode and manual mode. In automatic
135	  mode, it looks to the computer like a standard USB printer. Only
136	  printers may be connected to the USS-720 in this mode. The generic
137	  USB printer driver ("USB Printer support", above) may be used in
138	  that mode, and you can say N here if you want to use the chip only
139	  in this mode.
140
141	  Manual mode is not limited to printers, any parallel port
142	  device should work. This driver utilizes manual mode.
143	  Note however that some operations are three orders of magnitude
144	  slower than on a PCI/ISA Parallel Port, so timing critical
145	  applications might not work.
146
147	  Say Y here if you own an USS-720 USB->Parport cable and intend to
148	  connect anything other than a printer to it.
149
150	  To compile this driver as a module, choose M here: the
151	  module will be called uss720.

181	help
182	  UTMI+ Low Pin Interface (ULPI) is specification for a commonly used
183	  USB 2.0 PHY interface. The ULPI specification defines a standard set
184	  of registers that can be used to detect the vendor and product which
185	  allows ULPI to be handled as a bus. This module is the driver for that
186	  bus.
187
188	  The ULPI interfaces (the buses) are registered by the drivers for USB
189	  controllers which support ULPI register access and have ULPI PHY
190	  attached to them. The ULPI PHY drivers themselves are normal PHY
191	  drivers.
192
193	  ULPI PHYs provide often functions such as ADP sensing/probing (OTG
194	  protocol) and USB charger detection.
195
196	  To compile this driver as a module, choose M here: the module will
197	  be called ulpi.
