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


SYNOPSIS
     device ubtbcmfw


DESCRIPTION
     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 enpoint 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
