The bus supplies power to peripherals 63 and allows for hot swapping. Up to 127 USB peripherals can be 64 connected to a single USB host in a tree structure. 65 66 The USB host is the root of the tree, the peripherals are the 67 leaves and the inner nodes are special USB devices called hubs. 68 Most PCs now have USB host ports, used to connect peripherals 69 such as scanners, keyboards, mice, modems, cameras, disks, 70 flash memory, network links, and printers to the PC. 71 72 Say Y here if your computer has a host-side USB port and you want 73 to use USB devices. You then need to say Y to at least one of the 74 Host Controller Driver (HCD) options below. Choose a USB 1.1 75 controller, such as "UHCI HCD support" or "OHCI HCD support", 76 and "EHCI HCD (USB 2.0) support" except for older systems that 77 do not have USB 2.0 support. It doesn't normally hurt to select 78 them all if you are not certain. 79 80 If your system has a device-side USB port, used in the peripheral 81 side of the USB protocol, see the "USB Gadget" framework instead. 82 83 After choosing your HCD, then select drivers for the USB peripherals 84 you'll be using. You may want to check out the information provided 85 in <file:Documentation/usb/> and especially the links given in 86 <file:Documentation/usb/usb-help.txt>. 87 88 To compile this driver as a module, choose M here: the 89 module will be called usbcore. 90 91source "drivers/usb/core/Kconfig" 92 93source "drivers/usb/host/Kconfig" 94 95source "drivers/usb/class/Kconfig" 96 97source "drivers/usb/storage/Kconfig" 98 99source "drivers/usb/image/Kconfig" 100 101source "drivers/usb/mon/Kconfig" 102 103comment "USB port drivers" 104 depends on USB 105 106config USB_USS720 107 tristate "USS720 parport driver" 108 depends on USB && PARPORT 109 select PARPORT_NOT_PC 110 ---help--- 111 This driver is for USB parallel port adapters that use the Lucent 112 Technologies USS-720 chip. These cables are plugged into your USB 113 port and provide USB compatibility to peripherals designed with 114 parallel port interfaces. 115 116 The chip has two modes: automatic mode and manual mode. In automatic 117 mode, it looks to the computer like a standard USB printer. Only 118 printers may be connected to the USS-720 in this mode. The generic 119 USB printer driver ("USB Printer support", above) may be used in 120 that mode, and you can say N here if you want to use the chip only 121 in this mode. 122 123 Manual mode is not limited to printers, any parallel port 124 device should work. This driver utilizes manual mode. 125 Note however that some operations are three orders of magnitude 126 slower than on a PCI/ISA Parallel Port, so timing critical 127 applications might not work. 128 129 Say Y here if you own an USS-720 USB->Parport cable and intend to 130 connect anything other than a printer to it. 131 132 To compile this driver as a module, choose M here: the 133 module will be called uss720. 134 135source "drivers/usb/serial/Kconfig" 136 137source "drivers/usb/misc/Kconfig" 138 139source "drivers/usb/atm/Kconfig" 140 141source "drivers/usb/gadget/Kconfig" 142 143endif # USB_SUPPORT 144
