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

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