91 Universal Serial Bus (USB) is a specification for a serial bus
92 subsystem which offers higher speeds and more features than the
93 traditional PC serial port. The bus supplies power to peripherals
94 and allows for hot swapping. Up to 127 USB peripherals can be
95 connected to a single USB host in a tree structure.
96
97 The USB host is the root of the tree, the peripherals are the
98 leaves and the inner nodes are special USB devices called hubs.
99 Most PCs now have USB host ports, used to connect peripherals
100 such as scanners, keyboards, mice, modems, cameras, disks,
101 flash memory, network links, and printers to the PC.
102
103 Say Y here if your computer has a host-side USB port and you want
104 to use USB devices. You then need to say Y to at least one of the
105 Host Controller Driver (HCD) options below. Choose a USB 1.1
106 controller, such as "UHCI HCD support" or "OHCI HCD support",
107 and "EHCI HCD (USB 2.0) support" except for older systems that
108 do not have USB 2.0 support. It doesn't normally hurt to select
109 them all if you are not certain.
110
111 If your system has a device-side USB port, used in the peripheral
112 side of the USB protocol, see the "USB Gadget" framework instead.
113
114 After choosing your HCD, then select drivers for the USB peripherals
115 you'll be using. You may want to check out the information provided
116 in <file:Documentation/usb/> and especially the links given in
117 <file:Documentation/usb/usb-help.txt>.
118
119 To compile this driver as a module, choose M here: the
120 module will be called usbcore.

150 This driver is for USB parallel port adapters that use the Lucent
151 Technologies USS-720 chip. These cables are plugged into your USB
152 port and provide USB compatibility to peripherals designed with
153 parallel port interfaces.
154
155 The chip has two modes: automatic mode and manual mode. In automatic
156 mode, it looks to the computer like a standard USB printer. Only
157 printers may be connected to the USS-720 in this mode. The generic
158 USB printer driver ("USB Printer support", above) may be used in
159 that mode, and you can say N here if you want to use the chip only
160 in this mode.
161
162 Manual mode is not limited to printers, any parallel port
163 device should work. This driver utilizes manual mode.
164 Note however that some operations are three orders of magnitude
165 slower than on a PCI/ISA Parallel Port, so timing critical
166 applications might not work.
167
168 Say Y here if you own an USS-720 USB->Parport cable and intend to
169 connect anything other than a printer to it.
170
171 To compile this driver as a module, choose M here: the
172 module will be called uss720.
