55	  Universal Serial Bus (USB) is a specification for a serial bus
56	  subsystem which offers higher speeds and more features than the
57	  traditional PC serial port.  The bus supplies power to peripherals
58	  and allows for hot swapping.  Up to 127 USB peripherals can be
59	  connected to a single USB host in a tree structure.
60
61	  The USB host is the root of the tree, the peripherals are the
62	  leaves and the inner nodes are special USB devices called hubs.
63	  Most PCs now have USB host ports, used to connect peripherals
64	  such as scanners, keyboards, mice, modems, cameras, disks,
65	  flash memory, network links, and printers to the PC.
66
67	  Say Y here if your computer has a host-side USB port and you want
68	  to use USB devices.  You then need to say Y to at least one of the
69	  Host Controller Driver (HCD) options below.  Choose a USB 1.1
70	  controller, such as "UHCI HCD support" or "OHCI HCD support",
71	  and "EHCI HCD (USB 2.0) support" except for older systems that
72	  do not have USB 2.0 support.  It doesn't normally hurt to select
73	  them all if you are not certain.
74
75	  If your system has a device-side USB port, used in the peripheral
76	  side of the USB protocol, see the "USB Gadget" framework instead.
77
78	  After choosing your HCD, then select drivers for the USB peripherals
79	  you'll be using.  You may want to check out the information provided
80	  in <file:Documentation/usb/> and especially the links given in
81	  <file:Documentation/usb/usb-help.txt>.
82
83	  To compile this driver as a module, choose M here: the
84	  module will be called usbcore.

105	---help---
106	  This driver is for USB parallel port adapters that use the Lucent
107	  Technologies USS-720 chip. These cables are plugged into your USB
108	  port and provide USB compatibility to peripherals designed with
109	  parallel port interfaces.
110
111	  The chip has two modes: automatic mode and manual mode. In automatic
112	  mode, it looks to the computer like a standard USB printer. Only
113	  printers may be connected to the USS-720 in this mode. The generic
114	  USB printer driver ("USB Printer support", above) may be used in
115	  that mode, and you can say N here if you want to use the chip only
116	  in this mode.
117
118	  Manual mode is not limited to printers, any parallel port
119	  device should work. This driver utilizes manual mode.
120	  Note however that some operations are three orders of magnitude
121	  slower than on a PCI/ISA Parallel Port, so timing critical
122	  applications might not work.
123
124	  Say Y here if you own an USS-720 USB->Parport cable and intend to
125	  connect anything other than a printer to it.
126
127	  To compile this driver as a module, choose M here: the
128	  module will be called uss720.
