45	  Universal Serial Bus (USB) is a specification for a serial bus
46	  subsystem which offers higher speeds and more features than the
47	  traditional PC serial port.  The bus supplies power to peripherals
48	  and allows for hot swapping.  Up to 127 USB peripherals can be
49	  connected to a single USB host in a tree structure.
50
51	  The USB host is the root of the tree, the peripherals are the
52	  leaves and the inner nodes are special USB devices called hubs.
53	  Most PCs now have USB host ports, used to connect peripherals
54	  such as scanners, keyboards, mice, modems, cameras, disks,
55	  flash memory, network links, and printers to the PC.
56
57	  Say Y here if your computer has a host-side USB port and you want
58	  to use USB devices.  You then need to say Y to at least one of the
59	  Host Controller Driver (HCD) options below.  Choose a USB 1.1
60	  controller, such as "UHCI HCD support" or "OHCI HCD support",
61	  and "EHCI HCD (USB 2.0) support" except for older systems that
62	  do not have USB 2.0 support.  It doesn't normally hurt to select
63	  them all if you are not certain.
64
65	  If your system has a device-side USB port, used in the peripheral
66	  side of the USB protocol, see the "USB Gadget" framework instead.
67
68	  After choosing your HCD, then select drivers for the USB peripherals
69	  you'll be using.  You may want to check out the information provided
70	  in <file:Documentation/usb/> and especially the links given in
71	  <file:Documentation/usb/usb-help.txt>.
72
73	  To compile this driver as a module, choose M here: the
74	  module will be called usbcore.

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