The bus supplies power to peripherals 50 and allows for hot swapping. Up to 127 USB peripherals can be 51 connected to a single USB host in a tree structure. 52 53 The USB host is the root of the tree, the peripherals are the 54 leaves and the inner nodes are special USB devices called hubs. 55 Most PCs now have USB host ports, used to connect peripherals 56 such as scanners, keyboards, mice, modems, cameras, disks, 57 flash memory, network links, and printers to the PC. 58 59 Say Y here if your computer has a host-side USB port and you want 60 to use USB devices. You then need to say Y to at least one of the 61 Host Controller Driver (HCD) options below. Choose a USB 1.1 62 controller, such as "UHCI HCD support" or "OHCI HCD support", 63 and "EHCI HCD (USB 2.0) support" except for older systems that 64 do not have USB 2.0 support. It doesn't normally hurt to select 65 them all if you are not certain. 66 67 If your system has a device-side USB port, used in the peripheral 68 side of the USB protocol, see the "USB Gadget" framework instead. 69 70 After choosing your HCD, then select drivers for the USB peripherals 71 you'll be using. You may want to check out the information provided 72 in <file:Documentation/usb/> and especially the links given in 73 <file:Documentation/usb/usb-help.txt>. 74 75 To compile this driver as a module, choose M here: the 76 module will be called usbcore. 77 78source "drivers/usb/core/Kconfig" 79 80source "drivers/usb/host/Kconfig" 81 82source "drivers/usb/class/Kconfig" 83 84source "drivers/usb/storage/Kconfig" 85 86source "drivers/usb/input/Kconfig" 87 88source "drivers/usb/image/Kconfig" 89 90source "drivers/usb/net/Kconfig" 91 92source "drivers/usb/mon/Kconfig" 93 94comment "USB port drivers" 95 depends on USB 96 97config USB_USS720 98 tristate "USS720 parport driver" 99 depends on USB && PARPORT 100 select PARPORT_NOT_PC 101 ---help--- 102 This driver is for USB parallel port adapters that use the Lucent 103 Technologies USS-720 chip. These cables are plugged into your USB 104 port and provide USB compatibility to peripherals designed with 105 parallel port interfaces. 106 107 The chip has two modes: automatic mode and manual mode. In automatic 108 mode, it looks to the computer like a standard USB printer. Only 109 printers may be connected to the USS-720 in this mode. The generic 110 USB printer driver ("USB Printer support", above) may be used in 111 that mode, and you can say N here if you want to use the chip only 112 in this mode. 113 114 Manual mode is not limited to printers, any parallel port 115 device should work. This driver utilizes manual mode. 116 Note however that some operations are three orders of magnitude 117 slower than on a PCI/ISA Parallel Port, so timing critical 118 applications might not work. 119 120 Say Y here if you own an USS-720 USB->Parport cable and intend to 121 connect anything other than a printer to it. 122 123 To compile this driver as a module, choose M here: the 124 module will be called uss720. 125 126source "drivers/usb/serial/Kconfig" 127 128source "drivers/usb/misc/Kconfig" 129 130source "drivers/usb/atm/Kconfig" 131 132source "drivers/usb/gadget/Kconfig" 133 134endmenu 135 136
