The bus supplies power to peripherals 55 and allows for hot swapping. Up to 127 USB peripherals can be 56 connected to a single USB host in a tree structure. 57 58 The USB host is the root of the tree, the peripherals are the 59 leaves and the inner nodes are special USB devices called hubs. 60 Most PCs now have USB host ports, used to connect peripherals 61 such as scanners, keyboards, mice, modems, cameras, disks, 62 flash memory, network links, and printers to the PC. 63 64 Say Y here if your computer has a host-side USB port and you want 65 to use USB devices. You then need to say Y to at least one of the 66 Host Controller Driver (HCD) options below. Choose a USB 1.1 67 controller, such as "UHCI HCD support" or "OHCI HCD support", 68 and "EHCI HCD (USB 2.0) support" except for older systems that 69 do not have USB 2.0 support. It doesn't normally hurt to select 70 them all if you are not certain. 71 72 If your system has a device-side USB port, used in the peripheral 73 side of the USB protocol, see the "USB Gadget" framework instead. 74 75 After choosing your HCD, then select drivers for the USB peripherals 76 you'll be using. You may want to check out the information provided 77 in <file:Documentation/usb/> and especially the links given in 78 <file:Documentation/usb/usb-help.rst>. 79 80 To compile this driver as a module, choose M here: the 81 module will be called usbcore. 82 83config USB_PCI 84 bool "PCI based USB host interface" 85 depends on PCI 86 default y 87 ---help--- 88 Many embedded system SOCs (e.g. freescale T2080) have both 89 PCI and USB modules with the USB module directly controlled by 90 registers and having no relationship to the PCI module. 91 92 If you have such a device you may say N here and PCI related code 93 will not be built in the USB driver. 94 95if USB 96 97source "drivers/usb/core/Kconfig" 98 99source "drivers/usb/mon/Kconfig" 100 101source "drivers/usb/wusbcore/Kconfig" 102 103source "drivers/usb/host/Kconfig" 104 105source "drivers/usb/renesas_usbhs/Kconfig" 106 107source "drivers/usb/class/Kconfig" 108 109source "drivers/usb/storage/Kconfig" 110 111source "drivers/usb/image/Kconfig" 112 113source "drivers/usb/usbip/Kconfig" 114 115endif 116 117source "drivers/usb/cdns3/Kconfig" 118 119source "drivers/usb/mtu3/Kconfig" 120 121source "drivers/usb/musb/Kconfig" 122 123source "drivers/usb/dwc3/Kconfig" 124 125source "drivers/usb/dwc2/Kconfig" 126 127source "drivers/usb/chipidea/Kconfig" 128 129source "drivers/usb/isp1760/Kconfig" 130 131comment "USB port drivers" 132 133if USB 134 135config USB_USS720 136 tristate "USS720 parport driver" 137 depends on PARPORT 138 select PARPORT_NOT_PC 139 ---help--- 140 This driver is for USB parallel port adapters that use the Lucent 141 Technologies USS-720 chip. These cables are plugged into your USB 142 port and provide USB compatibility to peripherals designed with 143 parallel port interfaces. 144 145 The chip has two modes: automatic mode and manual mode. In automatic 146 mode, it looks to the computer like a standard USB printer. Only 147 printers may be connected to the USS-720 in this mode. The generic 148 USB printer driver ("USB Printer support", above) may be used in 149 that mode, and you can say N here if you want to use the chip only 150 in this mode. 151 152 Manual mode is not limited to printers, any parallel port 153 device should work. This driver utilizes manual mode. 154 Note however that some operations are three orders of magnitude 155 slower than on a PCI/ISA Parallel Port, so timing critical 156 applications might not work. 157 158 Say Y here if you own an USS-720 USB->Parport cable and intend to 159 connect anything other than a printer to it. 160 161 To compile this driver as a module, choose M here: the 162 module will be called uss720. 163 164source "drivers/usb/serial/Kconfig" 165 166source "drivers/usb/misc/Kconfig" 167 168source "drivers/usb/atm/Kconfig" 169 170endif # USB 171 172source "drivers/usb/phy/Kconfig" 173 174source "drivers/usb/gadget/Kconfig" 175 176source "drivers/usb/typec/Kconfig" 177 178source "drivers/usb/roles/Kconfig" 179 180config USB_LED_TRIG 181 bool "USB LED Triggers" 182 depends on LEDS_CLASS && LEDS_TRIGGERS 183 select USB_COMMON 184 help 185 This option adds LED triggers for USB host and/or gadget activity. 186 187 Say Y here if you are working on a system with led-class supported 188 LEDs and you want to use them as activity indicators for USB host or 189 gadget. 190 191config USB_ULPI_BUS 192 tristate "USB ULPI PHY interface support" 193 select USB_COMMON 194 help 195 UTMI+ Low Pin Interface (ULPI) is specification for a commonly used 196 USB 2.0 PHY interface.

This module is the driver for that 199 bus. 200 201 The ULPI interfaces (the buses) are registered by the drivers for USB 202 controllers which support ULPI register access and have ULPI PHY 203 attached to them. The ULPI PHY drivers themselves are normal PHY 204 drivers. 205 206 ULPI PHYs provide often functions such as ADP sensing/probing (OTG 207 protocol) and USB charger detection. 208 209 To compile this driver as a module, choose M here: the module will 210 be called ulpi. 211 212endif # USB_SUPPORT 213
