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

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