bcmfw – firmware download utility for Broadcom BCM2033 chip based Bluetooth USB devices



bcmfw [-h] -f firmware_file_name -m mini-driver_file_name -n device_name


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.
  Display usage message and exit.
-m mini-driver_file_name
  Specify mini-driver file name for download.
-n device_name
  Specify device name.


BCM2033-MD.hex Mini-driver image.
BCM2033-FW.bin Firmware image.
/dev/ubtbcmfwN .EE Endpoint EE of device N.


The utility exits 0 on success, and >0 if an error occurs.


To download the firmware into the /dev/ubtbcmfw0 device:

    bcmfw -n ubtbcmfw0 -m BCM2033-MD.hex -f BCM2033-FW.bin
