65	  Universal Serial Bus (USB) is a specification for a serial bus
66	  subsystem which offers higher speeds and more features than the
67	  traditional PC serial port.  The bus supplies power to peripherals
68	  and allows for hot swapping.  Up to 127 USB peripherals can be
69	  connected to a single USB host in a tree structure.
70
71	  The USB host is the root of the tree, the peripherals are the
72	  leaves and the inner nodes are special USB devices called hubs.
73	  Most PCs now have USB host ports, used to connect peripherals
74	  such as scanners, keyboards, mice, modems, cameras, disks,
75	  flash memory, network links, and printers to the PC.
76
77	  Say Y here if your computer has a host-side USB port and you want
78	  to use USB devices.  You then need to say Y to at least one of the
79	  Host Controller Driver (HCD) options below.  Choose a USB 1.1
80	  controller, such as "UHCI HCD support" or "OHCI HCD support",
81	  and "EHCI HCD (USB 2.0) support" except for older systems that
82	  do not have USB 2.0 support.  It doesn't normally hurt to select
83	  them all if you are not certain.
84
85	  If your system has a device-side USB port, used in the peripheral
86	  side of the USB protocol, see the "USB Gadget" framework instead.
87
88	  After choosing your HCD, then select drivers for the USB peripherals
89	  you'll be using.  You may want to check out the information provided
90	  in <file:Documentation/usb/> and especially the links given in
91	  <file:Documentation/usb/usb-help.txt>.
92
93	  To compile this driver as a module, choose M here: the
94	  module will be called usbcore.

116	  This driver is for USB parallel port adapters that use the Lucent
117	  Technologies USS-720 chip. These cables are plugged into your USB
118	  port and provide USB compatibility to peripherals designed with
119	  parallel port interfaces.
120
121	  The chip has two modes: automatic mode and manual mode. In automatic
122	  mode, it looks to the computer like a standard USB printer. Only
123	  printers may be connected to the USS-720 in this mode. The generic
124	  USB printer driver ("USB Printer support", above) may be used in
125	  that mode, and you can say N here if you want to use the chip only
126	  in this mode.
127
128	  Manual mode is not limited to printers, any parallel port
129	  device should work. This driver utilizes manual mode.
130	  Note however that some operations are three orders of magnitude
131	  slower than on a PCI/ISA Parallel Port, so timing critical
132	  applications might not work.
133
134	  Say Y here if you own an USS-720 USB->Parport cable and intend to
135	  connect anything other than a printer to it.
136
137	  To compile this driver as a module, choose M here: the
138	  module will be called uss720.
