The bus supplies power to peripherals 54 and allows for hot swapping. Up to 127 USB peripherals can be 55 connected to a single USB host in a tree structure. 56 57 The USB host is the root of the tree, the peripherals are the 58 leaves and the inner nodes are special USB devices called hubs. 59 Most PCs now have USB host ports, used to connect peripherals 60 such as scanners, keyboards, mice, modems, cameras, disks, 61 flash memory, network links, and printers to the PC. 62 63 Say Y here if your computer has a host-side USB port and you want 64 to use USB devices. You then need to say Y to at least one of the 65 Host Controller Driver (HCD) options below. Choose a USB 1.1 66 controller, such as "UHCI HCD support" or "OHCI HCD support", 67 and "EHCI HCD (USB 2.0) support" except for older systems that 68 do not have USB 2.0 support. It doesn't normally hurt to select 69 them all if you are not certain. 70 71 If your system has a device-side USB port, used in the peripheral 72 side of the USB protocol, see the "USB Gadget" framework instead. 73 74 After choosing your HCD, then select drivers for the USB peripherals 75 you'll be using. You may want to check out the information provided 76 in <file:Documentation/usb/> and especially the links given in 77 <file:Documentation/usb/usb-help.txt>. 78 79 To compile this driver as a module, choose M here: the 80 module will be called usbcore. 81 82config USB_PCI 83 bool "PCI based USB host interface" 84 depends on PCI 85 default y 86 ---help--- 87 Many embedded system SOCs (e.g. freescale T2080) have both 88 PCI and USB modules with the USB module directly controlled by 89 registers and having no relationship to the PCI module. 90 91 If you have such a device you may say N here and PCI related code 92 will not be built in the USB driver. 93 94if USB 95 96source "drivers/usb/core/Kconfig" 97 98source "drivers/usb/mon/Kconfig" 99 100source "drivers/usb/wusbcore/Kconfig" 101 102source "drivers/usb/host/Kconfig" 103 104source "drivers/usb/renesas_usbhs/Kconfig" 105 106source "drivers/usb/class/Kconfig" 107 108source "drivers/usb/storage/Kconfig" 109 110source "drivers/usb/image/Kconfig" 111 112source "drivers/usb/usbip/Kconfig" 113 114endif 115 116source "drivers/usb/mtu3/Kconfig" 117 118source "drivers/usb/musb/Kconfig" 119 120source "drivers/usb/dwc3/Kconfig" 121 122source "drivers/usb/dwc2/Kconfig" 123 124source "drivers/usb/chipidea/Kconfig" 125 126source "drivers/usb/isp1760/Kconfig" 127 128comment "USB port drivers" 129 130if USB 131 132config USB_USS720 133 tristate "USS720 parport driver" 134 depends on PARPORT 135 select PARPORT_NOT_PC 136 ---help--- 137 This driver is for USB parallel port adapters that use the Lucent 138 Technologies USS-720 chip. These cables are plugged into your USB 139 port and provide USB compatibility to peripherals designed with 140 parallel port interfaces. 141 142 The chip has two modes: automatic mode and manual mode. In automatic 143 mode, it looks to the computer like a standard USB printer. Only 144 printers may be connected to the USS-720 in this mode. The generic 145 USB printer driver ("USB Printer support", above) may be used in 146 that mode, and you can say N here if you want to use the chip only 147 in this mode. 148 149 Manual mode is not limited to printers, any parallel port 150 device should work. This driver utilizes manual mode. 151 Note however that some operations are three orders of magnitude 152 slower than on a PCI/ISA Parallel Port, so timing critical 153 applications might not work. 154 155 Say Y here if you own an USS-720 USB->Parport cable and intend to 156 connect anything other than a printer to it. 157 158 To compile this driver as a module, choose M here: the 159 module will be called uss720. 160 161source "drivers/usb/serial/Kconfig" 162 163source "drivers/usb/misc/Kconfig" 164 165source "drivers/usb/atm/Kconfig" 166 167endif # USB 168 169source "drivers/usb/phy/Kconfig" 170 171source "drivers/usb/gadget/Kconfig" 172 173source "drivers/usb/typec/Kconfig" 174 175source "drivers/usb/roles/Kconfig" 176 177config USB_LED_TRIG 178 bool "USB LED Triggers" 179 depends on LEDS_CLASS && LEDS_TRIGGERS 180 select USB_COMMON 181 help 182 This option adds LED triggers for USB host and/or gadget activity. 183 184 Say Y here if you are working on a system with led-class supported 185 LEDs and you want to use them as activity indicators for USB host or 186 gadget. 187 188config USB_ULPI_BUS 189 tristate "USB ULPI PHY interface support" 190 select USB_COMMON 191 help 192 UTMI+ Low Pin Interface (ULPI) is specification for a commonly used 193 USB 2.0 PHY interface.

This module is the driver for that 196 bus. 197 198 The ULPI interfaces (the buses) are registered by the drivers for USB 199 controllers which support ULPI register access and have ULPI PHY 200 attached to them. The ULPI PHY drivers themselves are normal PHY 201 drivers. 202 203 ULPI PHYs provide often functions such as ADP sensing/probing (OTG 204 protocol) and USB charger detection. 205 206 To compile this driver as a module, choose M here: the module will 207 be called ulpi. 208 209endif # USB_SUPPORT 210
