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

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