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

105 This driver is for USB parallel port adapters that use the Lucent
106 Technologies USS-720 chip. These cables are plugged into your USB
107 port and provide USB compatibility to peripherals designed with
108 parallel port interfaces.
110 The chip has two modes: automatic mode and manual mode. In automatic
111 mode, it looks to the computer like a standard USB printer. Only
112 printers may be connected to the USS-720 in this mode. The generic
113 USB printer driver ("USB Printer support", above) may be used in
114 that mode, and you can say N here if you want to use the chip only
117 Manual mode is not limited to printers, any parallel port
118 device should work. This driver utilizes manual mode.
119 Note however that some operations are three orders of magnitude
120 slower than on a PCI/ISA Parallel Port, so timing critical
121 applications might not work.
123 Say Y here if you own an USS-720 USB->Parport cable and intend to
124 connect anything other than a printer to it.
126 To compile this driver as a module, choose M here: the
127 module will be called uss720.
