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. 44 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. 50 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. 58 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. 61 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>. 66 67 To compile this driver as a module, choose M here: the 68 module will be called usbcore. 69 70if USB 71 72source "drivers/usb/core/Kconfig" 73 74source "drivers/usb/mon/Kconfig" 75 76source "drivers/usb/wusbcore/Kconfig" 77 78source "drivers/usb/host/Kconfig" 79 80source "drivers/usb/musb/Kconfig" 81 82source "drivers/usb/renesas_usbhs/Kconfig" 83 84source "drivers/usb/class/Kconfig" 85 86source "drivers/usb/storage/Kconfig" 87 88source "drivers/usb/image/Kconfig" 89 90endif 91 92source "drivers/usb/dwc3/Kconfig" 93 94source "drivers/usb/chipidea/Kconfig" 95 96comment "USB port drivers" 97 98if USB 99 100config USB_USS720 101 tristate "USS720 parport driver" 102 depends on PARPORT 103 select PARPORT_NOT_PC 104 ---help--- 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. 109 110 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 115 in this mode. 116 117 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. 122 123 Say Y here if you own an USS-720 USB->Parport cable and intend to 124 connect anything other than a printer to it. 125 126 To compile this driver as a module, choose M here: the 127 module will be called uss720. 128 129source "drivers/usb/serial/Kconfig" 130 131source "drivers/usb/misc/Kconfig" 132 133source "drivers/usb/atm/Kconfig" 134 135endif # USB 136 137source "drivers/usb/phy/Kconfig" 138 139source "drivers/usb/gadget/Kconfig" 140 141endif # USB_SUPPORT 142
