71	  Universal Serial Bus (USB) is a specification for a serial bus
72	  subsystem which offers higher speeds and more features than the
73	  traditional PC serial port.  The bus supplies power to peripherals
74	  and allows for hot swapping.  Up to 127 USB peripherals can be
75	  connected to a single USB host in a tree structure.
76
77	  The USB host is the root of the tree, the peripherals are the
78	  leaves and the inner nodes are special USB devices called hubs.
79	  Most PCs now have USB host ports, used to connect peripherals
80	  such as scanners, keyboards, mice, modems, cameras, disks,
81	  flash memory, network links, and printers to the PC.
82
83	  Say Y here if your computer has a host-side USB port and you want
84	  to use USB devices.  You then need to say Y to at least one of the
85	  Host Controller Driver (HCD) options below.  Choose a USB 1.1
86	  controller, such as "UHCI HCD support" or "OHCI HCD support",
87	  and "EHCI HCD (USB 2.0) support" except for older systems that
88	  do not have USB 2.0 support.  It doesn't normally hurt to select
89	  them all if you are not certain.
90
91	  If your system has a device-side USB port, used in the peripheral
92	  side of the USB protocol, see the "USB Gadget" framework instead.
93
94	  After choosing your HCD, then select drivers for the USB peripherals
95	  you'll be using.  You may want to check out the information provided
96	  in <file:Documentation/usb/> and especially the links given in
97	  <file:Documentation/usb/usb-help.txt>.
98
99	  To compile this driver as a module, choose M here: the
100	  module will be called usbcore.

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