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>. 83 84 To compile this driver as a module, choose M here: the 85 module will be called usbcore. 86 87if USB 88 89source "drivers/usb/core/Kconfig" 90 91source "drivers/usb/mon/Kconfig" 92 93source "drivers/usb/wusbcore/Kconfig" 94 95source "drivers/usb/host/Kconfig" 96 97source "drivers/usb/renesas_usbhs/Kconfig" 98 99source "drivers/usb/class/Kconfig" 100 101source "drivers/usb/storage/Kconfig" 102 103source "drivers/usb/image/Kconfig" 104 105endif 106 107source "drivers/usb/musb/Kconfig" 108 109source "drivers/usb/dwc3/Kconfig" 110 111source "drivers/usb/dwc2/Kconfig" 112 113source "drivers/usb/chipidea/Kconfig" 114 115comment "USB port drivers" 116 117if USB 118 119config USB_USS720 120 tristate "USS720 parport driver" 121 depends on PARPORT 122 select PARPORT_NOT_PC 123 ---help--- 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. 147 148source "drivers/usb/serial/Kconfig" 149 150source "drivers/usb/misc/Kconfig" 151 152source "drivers/usb/atm/Kconfig" 153 154endif # USB 155 156source "drivers/usb/phy/Kconfig" 157 158source "drivers/usb/gadget/Kconfig" 159 160endif # USB_SUPPORT 161
