The bus supplies power to peripherals 47 and allows for hot swapping. Up to 127 USB peripherals can be 48 connected to a single USB host in a tree structure. 49 50 The USB host is the root of the tree, the peripherals are the 51 leaves and the inner nodes are special USB devices called hubs. 52 Most PCs now have USB host ports, used to connect peripherals 53 such as scanners, keyboards, mice, modems, cameras, disks, 54 flash memory, network links, and printers to the PC. 55 56 Say Y here if your computer has a host-side USB port and you want 57 to use USB devices. You then need to say Y to at least one of the 58 Host Controller Driver (HCD) options below. Choose a USB 1.1 59 controller, such as "UHCI HCD support" or "OHCI HCD support", 60 and "EHCI HCD (USB 2.0) support" except for older systems that 61 do not have USB 2.0 support. It doesn't normally hurt to select 62 them all if you are not certain. 63 64 If your system has a device-side USB port, used in the peripheral 65 side of the USB protocol, see the "USB Gadget" framework instead. 66 67 After choosing your HCD, then select drivers for the USB peripherals 68 you'll be using. You may want to check out the information provided 69 in <file:Documentation/usb/> and especially the links given in 70 <file:Documentation/usb/usb-help.txt>. 71 72 To compile this driver as a module, choose M here: the 73 module will be called usbcore. 74 75config USB_PCI 76 bool "PCI based USB host interface" 77 depends on PCI 78 default y 79 ---help--- 80 Many embedded system SOCs (e.g. freescale T2080) have both 81 PCI and USB modules with the USB module directly controlled by 82 registers and having no relationship to the PCI module. 83 84 If you have such a device you may say N here and PCI related code 85 will not be built in the USB driver. 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 105source "drivers/usb/usbip/Kconfig" 106 107endif 108 109source "drivers/usb/mtu3/Kconfig" 110 111source "drivers/usb/musb/Kconfig" 112 113source "drivers/usb/dwc3/Kconfig" 114 115source "drivers/usb/dwc2/Kconfig" 116 117source "drivers/usb/chipidea/Kconfig" 118 119source "drivers/usb/isp1760/Kconfig" 120 121comment "USB port drivers" 122 123if USB 124 125config USB_USS720 126 tristate "USS720 parport driver" 127 depends on PARPORT 128 select PARPORT_NOT_PC 129 ---help--- 130 This driver is for USB parallel port adapters that use the Lucent 131 Technologies USS-720 chip. These cables are plugged into your USB 132 port and provide USB compatibility to peripherals designed with 133 parallel port interfaces. 134 135 The chip has two modes: automatic mode and manual mode. In automatic 136 mode, it looks to the computer like a standard USB printer. Only 137 printers may be connected to the USS-720 in this mode. The generic 138 USB printer driver ("USB Printer support", above) may be used in 139 that mode, and you can say N here if you want to use the chip only 140 in this mode. 141 142 Manual mode is not limited to printers, any parallel port 143 device should work. This driver utilizes manual mode. 144 Note however that some operations are three orders of magnitude 145 slower than on a PCI/ISA Parallel Port, so timing critical 146 applications might not work. 147 148 Say Y here if you own an USS-720 USB->Parport cable and intend to 149 connect anything other than a printer to it. 150 151 To compile this driver as a module, choose M here: the 152 module will be called uss720. 153 154source "drivers/usb/serial/Kconfig" 155 156source "drivers/usb/misc/Kconfig" 157 158source "drivers/usb/atm/Kconfig" 159 160endif # USB 161 162source "drivers/usb/phy/Kconfig" 163 164source "drivers/usb/gadget/Kconfig" 165 166source "drivers/usb/typec/Kconfig" 167 168config USB_LED_TRIG 169 bool "USB LED Triggers" 170 depends on LEDS_CLASS && LEDS_TRIGGERS 171 select USB_COMMON 172 help 173 This option adds LED triggers for USB host and/or gadget activity. 174 175 Say Y here if you are working on a system with led-class supported 176 LEDs and you want to use them as activity indicators for USB host or 177 gadget. 178 179config USB_ULPI_BUS 180 tristate "USB ULPI PHY interface support" 181 select USB_COMMON 182 help 183 UTMI+ Low Pin Interface (ULPI) is specification for a commonly used 184 USB 2.0 PHY interface.

This module is the driver for that 187 bus. 188 189 The ULPI interfaces (the buses) are registered by the drivers for USB 190 controllers which support ULPI register access and have ULPI PHY 191 attached to them. The ULPI PHY drivers themselves are normal PHY 192 drivers. 193 194 ULPI PHYs provide often functions such as ADP sensing/probing (OTG 195 protocol) and USB charger detection. 196 197 To compile this driver as a module, choose M here: the module will 198 be called ulpi. 199 200endif # USB_SUPPORT 201
