UBTBCMFW(4)	       FreeBSD Kernel Interfaces Manual		   UBTBCMFW(4)

NAME
     ubtbcmfw -- Firmware driver for Broadcom BCM2033 chip based Bluetooth USB
     devices

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

	   device ubtbcmfw

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

	   ubtbcmfw_load="YES"

DESCRIPTION
     The ubtbcmfw is a firmware	driver for Broadcom BCM2033 chip based Blue-
     tooth USB devices.	 It provides minimal access to the parts of the	device
     required to download firmware.

     The ubtbcmfw driver creates three fixed endpoint device nodes.

     The control transfers can only happen on the control endpoint which is
     always endpoint 0.	 Control requests are issued by	ioctl(2) calls.

     Only incoming transfers are supported on an interrupt endpoint.  To per-
     form I/O on an interrupt endpoint,	read(2)	should be used.	 All I/O oper-
     ations on an interrupt endpoint are unbuffered.  Interrupt	endpoint is
     always endpoint 1.

     Only outgoing bulk	transfers are supported	on a bulk endpoint.  To	per-
     form I/O on a bulk	endpoint, write(2) should be used.  All	I/O operations
     on	a bulk endpoint	are unbuffered.	 Outgoing bulk endpoint	is always end-
     point 2.

     The control endpoint (endpoint 0) handles the following ioctl(2) calls:

     USB_GET_DEVICE_DESC (usb_device_descriptor_t)
	     Return the	device descriptor.

FILES
     /dev/ubtbcmfwN.EE	Endpoint EE of device N.
