0051 Universal Serial Bus (USB) is a specification for a serial bus
0052 subsystem which offers higher speeds and more features than the
0053 traditional PC serial port. The bus supplies power to peripherals
0054 and allows for hot swapping. Up to 127 USB peripherals can be
0055 connected to a single USB host in a tree structure.
0056
0057 The USB host is the root of the tree, the peripherals are the
0058 leaves and the inner nodes are special USB devices called hubs.
0059 Most PCs now have USB host ports, used to connect peripherals
0060 such as scanners, keyboards, mice, modems, cameras, disks,
0061 flash memory, network links, and printers to the PC.
0062
0063 Say Y here if your computer has a host-side USB port and you want
0064 to use USB devices. You then need to say Y to at least one of the
0065 Host Controller Driver (HCD) options below. Choose a USB 1.1
0066 controller, such as "UHCI HCD support" or "OHCI HCD support",
0067 and "EHCI HCD (USB 2.0) support" except for older systems that
0068 do not have USB 2.0 support. It doesn't normally hurt to select
0069 them all if you are not certain.
0070
0071 If your system has a device-side USB port, used in the peripheral
0072 side of the USB protocol, see the "USB Gadget" framework instead.
0073
0074 After choosing your HCD, then select drivers for the USB peripherals
0075 you'll be using. You may want to check out the information provided
0076 in <file:Documentation/usb/> and especially the links given in
0077 <file:Documentation/usb/usb-help.rst>.

0137 This driver is for USB parallel port adapters that use the Lucent
0138 Technologies USS-720 chip. These cables are plugged into your USB
0139 port and provide USB compatibility to peripherals designed with
0140 parallel port interfaces.
0141
0142 The chip has two modes: automatic mode and manual mode. In automatic
0143 mode, it looks to the computer like a standard USB printer. Only
0144 printers may be connected to the USS-720 in this mode. The generic
0145 USB printer driver ("USB Printer support", above) may be used in
0146 that mode, and you can say N here if you want to use the chip only
0147 in this mode.
0148
0149 Manual mode is not limited to printers, any parallel port
0150 device should work. This driver utilizes manual mode.
0151 Note however that some operations are three orders of magnitude
0152 slower than on a PCI/ISA Parallel Port, so timing critical
0153 applications might not work.
0154
0155 Say Y here if you own an USS-720 USB->Parport cable and intend to
0156 connect anything other than a printer to it.
0157
0158 To compile this driver as a module, choose M here: the
0159 module will be called uss720.
