Host-side USB depends on having a host controller

NOTE: dummy_hcd is always an option, but it's ignored here ...

NOTE: SL-811 option should be board-specific ...

config USB_ARCH_HAS_HCD boolean default y if USB_ARCH_HAS_OHCI default y if USB_ARCH_HAS_EHCI default y if ARM # SL-811 default PCI

many non-PCI SOC chips embed OHCI

config USB_ARCH_HAS_OHCI boolean # ARM: default y if SA1111 default y if ARCH_OMAP default y if ARCH_LH7A404 default y if ARCH_S3C2410 default y if PXA27x default y if ARCH_AT91RM9200 # PPC: default y if STB03xxx default y if PPC_MPC52xx # MIPS: default y if SOC_AU1X00 # more: default PCI

some non-PCI hcds implement EHCI

config USB_ARCH_HAS_EHCI boolean default y if PPC_83xx default y if SOC_AU1200 default PCI

ARM SA1111 chips have a non-PCI based "OHCI-compatible" USB host interface.

config USB tristate "Support for Host-side USB" depends on USB_ARCH_HAS_HCD ---help--- Universal Serial Bus (USB) is a specification for a serial bus subsystem which offers higher speeds and more features than the traditional PC serial port. The bus supplies power to peripherals and allows for hot swapping. Up to 127 USB peripherals can be connected to a single USB host in a tree structure.

  The USB host is the root of the tree, the peripherals are the
  leaves and the inner nodes are special USB devices called hubs.
  Most PCs now have USB host ports, used to connect peripherals
  such as scanners, keyboards, mice, modems, cameras, disks,
  flash memory, network links, and printers to the PC.

  Say Y here if your computer has a host-side USB port and you want
  to use USB devices.  You then need to say Y to at least one of the
  Host Controller Driver (HCD) options below.  Choose a USB 1.1
  controller, such as "UHCI HCD support" or "OHCI HCD support",
  and "EHCI HCD (USB 2.0) support" except for older systems that
  do not have USB 2.0 support.  It doesn't normally hurt to select
  them all if you are not certain.

  If your system has a device-side USB port, used in the peripheral
  side of the USB protocol, see the "USB Gadget" framework instead.

  After choosing your HCD, then select drivers for the USB peripherals
  you'll be using.  You may want to check out the information provided
  in <file:Documentation/usb/> and especially the links given in
  <file:Documentation/usb/usb-help.txt>.

  To compile this driver as a module, choose M here: the
  module will be called usbcore.

comment "USB port drivers" depends on USB

config USB_USS720 tristate "USS720 parport driver" depends on USB && PARPORT select PARPORT_NOT_PC ---help--- This driver is for USB parallel port adapters that use the Lucent Technologies USS-720 chip. These cables are plugged into your USB port and provide USB compatibility to peripherals designed with parallel port interfaces.

  The chip has two modes: automatic mode and manual mode. In automatic
  mode, it looks to the computer like a standard USB printer. Only
  printers may be connected to the USS-720 in this mode. The generic
  USB printer driver ("USB Printer support", above) may be used in
  that mode, and you can say N here if you want to use the chip only
  in this mode.

  Manual mode is not limited to printers, any parallel port
  device should work. This driver utilizes manual mode.
  Note however that some operations are three orders of magnitude
  slower than on a PCI/ISA Parallel Port, so timing critical
  applications might not work.

  Say Y here if you own an USS-720 USB->Parport cable and intend to
  connect anything other than a printer to it.

  To compile this driver as a module, choose M here: the
  module will be called uss720.
