       The  ubtbcmfw  is  a  firmware driver for Broadcom BCM2033 chip based Bluetooth 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 perform I/O on an interrupt endpoint,
       read(2)  should be used.  All I/O operations on an interrupt endpoint are unbuffered.  Interrupt endpoint
       is always endpoint 1.

       Only outgoing bulk transfers are supported on a bulk endpoint.   To  perform  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 endpoint 2.

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

       USB_GET_DEVICE_DESC (usb_device_descriptor_t)
               Return the device descriptor.

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

       The ubtbcmfw driver was implemented in FreeBSD 5.0.

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

             deviceubtbcmfw

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