# # USB device configuration # menu "USB support" # ARM SA1111 chips have a non-PCI based "OHCI-compatible" USB host interface. config USB tristate "Support for USB" depends on PCI || SA1111 || ARCH_OMAP1510 || ARCH_OMAP1610 ---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 port in a tree structure. The USB port is the root of the tree, the peripherals are the leaves and the inner nodes are special USB devices called hubs. Many newer PC's have USB ports and newer peripherals such as scanners, keyboards, mice, modems, and printers support the USB protocol and can be connected to the PC via those ports. Say Y here if your computer has a USB port and you want to use USB devices. You then need to say Y to at least one of "UHCI HCD support" or "OHCI HCD support" below (the type of interface that the USB hardware in your computer provides to the operating system) and then choose from amongst the drivers for USB peripherals. 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>. If you have a new USB 2.0 High Speed system, you should also choose "EHCI HCD (USB 2.0) support" as well as at least one of UHCI or OHCI. It doesn't normally hurt to select them all if you are not certain. To compile this driver as a module, choose M here: the module will be called usbcore. source "drivers/usb/core/Kconfig" source "drivers/usb/host/Kconfig" source "drivers/usb/class/Kconfig" source "drivers/usb/storage/Kconfig" source "drivers/usb/input/Kconfig" source "drivers/usb/image/Kconfig" source "drivers/usb/media/Kconfig" source "drivers/usb/net/Kconfig" comment "USB port drivers" depends on USB config USB_USS720 tristate "USS720 parport driver" depends on USB && PARPORT ---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. source "drivers/usb/serial/Kconfig" source "drivers/usb/misc/Kconfig" source "drivers/usb/gadget/Kconfig" endmenu
