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

86	help
87	  Many embedded system SOCs (e.g. freescale T2080) have both
88	  PCI and USB modules with the USB module directly controlled by
89	  registers and having no relationship to the PCI module.
90
91	  If you have such a device you may say N here and PCI related code
92	  will not be built in the USB driver.

137	  This driver is for USB parallel port adapters that use the Lucent
138	  Technologies USS-720 chip. These cables are plugged into your USB
139	  port and provide USB compatibility to peripherals designed with
140	  parallel port interfaces.
141
142	  The chip has two modes: automatic mode and manual mode. In automatic
143	  mode, it looks to the computer like a standard USB printer. Only
144	  printers may be connected to the USS-720 in this mode. The generic
145	  USB printer driver ("USB Printer support", above) may be used in
146	  that mode, and you can say N here if you want to use the chip only
147	  in this mode.
148
149	  Manual mode is not limited to printers, any parallel port
150	  device should work. This driver utilizes manual mode.
151	  Note however that some operations are three orders of magnitude
152	  slower than on a PCI/ISA Parallel Port, so timing critical
153	  applications might not work.
154
155	  Say Y here if you own an USS-720 USB->Parport cable and intend to
156	  connect anything other than a printer to it.
157
158	  To compile this driver as a module, choose M here: the
159	  module will be called uss720.
