11 You will also need drivers from the following menu to make use of it.

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

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