49	---help---
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.
55
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.
61
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.
69
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.
72
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>.
77
78	  To compile this driver as a module, choose M here: the
79	  module will be called usbcore.
80
81config USB_PCI
82	bool "PCI based USB host interface"
83	depends on PCI
84	default y
85	---help---
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.
89
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.

135	---help---
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.
140
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
146	  in this mode.
147
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.
153
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.
156
157	  To compile this driver as a module, choose M here: the
158	  module will be called uss720.

190	help
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
195	  bus.
196
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
200	  drivers.
201
202	  ULPI PHYs provide often functions such as ADP sensing/probing (OTG
203	  protocol) and USB charger detection.
204
205	  To compile this driver as a module, choose M here: the module will
206	  be called ulpi.
