92	  Universal Serial Bus (USB) is a specification for a serial bus
93	  subsystem which offers higher speeds and more features than the
94	  traditional PC serial port.  The bus supplies power to peripherals
95	  and allows for hot swapping.  Up to 127 USB peripherals can be
96	  connected to a single USB host in a tree structure.
97	  
98	  The USB host is the root of the tree, the peripherals are the
99	  leaves and the inner nodes are special USB devices called hubs.
100	  Most PCs now have USB host ports, used to connect peripherals
101	  such as scanners, keyboards, mice, modems, cameras, disks,
102	  flash memory, network links, and printers to the PC.
103
104	  Say Y here if your computer has a host-side USB port and you want
105	  to use USB devices.  You then need to say Y to at least one of the
106	  Host Controller Driver (HCD) options below.  Choose a USB 1.1
107	  controller, such as "UHCI HCD support" or "OHCI HCD support",
108	  and "EHCI HCD (USB 2.0) support" except for older systems that
109	  do not have USB 2.0 support.  It doesn't normally hurt to select
110	  them all if you are not certain.
111
112	  If your system has a device-side USB port, used in the peripheral
113	  side of the USB protocol, see the "USB Gadget" framework instead.
114
115	  After choosing your HCD, then select drivers for the USB peripherals
116	  you'll be using.  You may want to check out the information provided
117	  in <file:Documentation/usb/> and especially the links given in
118	  <file:Documentation/usb/usb-help.txt>.
119
120	  To compile this driver as a module, choose M here: the
121	  module will be called usbcore.

151	  This driver is for USB parallel port adapters that use the Lucent
152	  Technologies USS-720 chip. These cables are plugged into your USB
153	  port and provide USB compatibility to peripherals designed with
154	  parallel port interfaces.
155
156	  The chip has two modes: automatic mode and manual mode. In automatic
157	  mode, it looks to the computer like a standard USB printer. Only
158	  printers may be connected to the USS-720 in this mode. The generic
159	  USB printer driver ("USB Printer support", above) may be used in
160	  that mode, and you can say N here if you want to use the chip only
161	  in this mode.
162
163	  Manual mode is not limited to printers, any parallel port
164	  device should work. This driver utilizes manual mode.
165	  Note however that some operations are three orders of magnitude
166	  slower than on a PCI/ISA Parallel Port, so timing critical
167	  applications might not work.
168
169	  Say Y here if you own an USS-720 USB->Parport cable and intend to
170	  connect anything other than a printer to it.
171
172	  To compile this driver as a module, choose M here: the
173	  module will be called uss720.
