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

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