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

 84           To compile this driver as a module, choose M here: the
 85           module will be called usbcore.

124           This driver is for USB parallel port adapters that use the Lucent
125           Technologies USS-720 chip. These cables are plugged into your USB
126           port and provide USB compatibility to peripherals designed with
127           parallel port interfaces.
128 
129           The chip has two modes: automatic mode and manual mode. In automatic
130           mode, it looks to the computer like a standard USB printer. Only
131           printers may be connected to the USS-720 in this mode. The generic
132           USB printer driver ("USB Printer support", above) may be used in
133           that mode, and you can say N here if you want to use the chip only
134           in this mode.
135 
136           Manual mode is not limited to printers, any parallel port
137           device should work. This driver utilizes manual mode.
138           Note however that some operations are three orders of magnitude
139           slower than on a PCI/ISA Parallel Port, so timing critical
140           applications might not work.
141 
142           Say Y here if you own an USS-720 USB->Parport cable and intend to
143           connect anything other than a printer to it.
144 
145           To compile this driver as a module, choose M here: the
146           module will be called uss720.
