USB_BUS_START_ENUM(9)					       Host Controller APIs					     USB_BUS_START_ENUM(9)

NAME

       usb_bus_start_enum - start immediate enumeration (for OTG)

SYNOPSIS

       int usb_bus_start_enum(struct usb_bus * bus, unsigned port_num);

ARGUMENTS

       bus
	   the bus (must use hcd framework)

       port_num
	   1-based number of port; usually bus->otg_port

CONTEXT

       in_interrupt

DESCRIPTION

       Starts enumeration, with an immediate reset followed later by khubd identifying and possibly configuring the device. This is needed by OTG
       controller drivers, where it helps meet HNP protocol timing requirements for starting a port reset.

RETURN

       0 if successful.

NAME

     firewire -- IEEE1394 High-performance Serial Bus

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device firewire

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   firewire_load="YES"

DESCRIPTION

     FreeBSD provides machine-independent bus support and raw drivers for firewire interfaces.

     The firewire driver consists of two layers: the controller and the bus layer.  The controller attaches to a physical bus (like pci(4)).  The
     firewire bus attaches to the controller.  Additional drivers can be attached to the bus.

     Up to 63 devices, including the host itself, can be attached to a firewire bus.  The root node is dynamically assigned with a PHY device
     function.	Also, the other firewire bus specific parameters, e.g., node ID, cycle master, isochronous resource manager and bus manager, are
     dynamically assigned, after bus reset is initiated.  On the firewire bus, every device is identified by an EUI 64 address.
