UBTBCMFW(4)              BSD Kernel Interfaces Manual              UBTBCMFW(4)

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 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
     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.

BUGS
     Most likely.  Please report if found.

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