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 A lot of embeded system SOC (e.g. freescale T2080) have both 81 PCI and USB modules.

These cables are plugged into your USB 131 port and provide USB compatibility to peripherals designed with 132 parallel port interfaces. 133 134 The chip has two modes: automatic mode and manual mode. In automatic 135 mode, it looks to the computer like a standard USB printer. Only 136 printers may be connected to the USS-720 in this mode. The generic 137 USB printer driver ("USB Printer support", above) may be used in 138 that mode, and you can say N here if you want to use the chip only 139 in this mode. 140 141 Manual mode is not limited to printers, any parallel port 142 device should work. This driver utilizes manual mode. 143 Note however that some operations are three orders of magnitude 144 slower than on a PCI/ISA Parallel Port, so timing critical 145 applications might not work. 146 147 Say Y here if you own an USS-720 USB->Parport cable and intend to 148 connect anything other than a printer to it. 149 150 To compile this driver as a module, choose M here: the 151 module will be called uss720. 152 153source "drivers/usb/serial/Kconfig" 154 155source "drivers/usb/misc/Kconfig" 156 157source "drivers/usb/atm/Kconfig" 158 159endif # USB 160 161source "drivers/usb/phy/Kconfig" 162 163source "drivers/usb/gadget/Kconfig" 164 165source "drivers/usb/typec/Kconfig" 166 167config USB_LED_TRIG 168 bool "USB LED Triggers" 169 depends on LEDS_CLASS && LEDS_TRIGGERS 170 select USB_COMMON 171 help 172 This option adds LED triggers for USB host and/or gadget activity. 173 174 Say Y here if you are working on a system with led-class supported 175 LEDs and you want to use them as activity indicators for USB host or 176 gadget. 177 178config USB_ULPI_BUS 179 tristate "USB ULPI PHY interface support" 180 select USB_COMMON 181 help 182 UTMI+ Low Pin Interface (ULPI) is specification for a commonly used 183 USB 2.0 PHY interface.

This module is the driver for that 186 bus. 187 188 The ULPI interfaces (the buses) are registered by the drivers for USB 189 controllers which support ULPI register access and have ULPI PHY 190 attached to them.
