bcmfw -- firmware download utility for Broadcom BCM2033 chip based Bluetooth USB devices
SYNOPSIS
bcmfw [-h] -f firmware_file_name -m mini-driver_file_name -n device_name
DESCRIPTION
The bcmfw utility downloads the specified mini-driver and firmware files to the specified device.
This utility will only work with Broadcom BCM2033 chip based Bluetooth USB devices. The identification is currently based on USB vendor
ID/product ID pair. The vendor ID should be 0x0a5c (USB_VENDOR_BROADCOM) and the product ID should be 0x2033.
Due to copyright issues I will no longer provide mini-driver and firmware files for the device. These files can be obtained from the Linux
BlueZ bluez-firmware package.
Visit http://www.bluez.org/download.html for details.
I am using the following files from the bluez-firmware-1.0 package:
MD5 (BCM2033-MD.hex) = 5580317158d07fc4ace90af04f8e1c73
MD5 (BCM2033-FW.bin) = b4e142b3272cfe5a84b32fda6b4b032f
The options are as follows:
-f firmware_file_name
Specify firmware file name for download.
-h Display usage message and exit.
-m mini-driver_file_name
Specify mini-driver file name for download.
-n device_name
Specify device name.
FILES
BCM2033-MD.hex Mini-driver image.
BCM2033-FW.bin Firmware image.
/dev/ubtbcmfwN.EE Endpoint EE of device N.
EXIT STATUS
The bcmfw utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
To download the firmware into the /dev/ubtbcmfw0 device:
bcmfw -n ubtbcmfw0 -m BCM2033-MD.hex -f BCM2033-FW.bin

UBTBCMFW(4) BSD 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 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 opera-
tions 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.
FILES
/dev/ubtbcmfwN.EE Endpoint EE of device N.
SEE ALSO ng_ubt(4), ugen(4), usb(4), bcmfw(8)HISTORY
The ubtbcmfw driver was implemented in FreeBSD 5.0.
