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.
