# bcmfw(8)

load firmware for Broadcom BCM2033 Bluetooth USB devices

## NAME

**bcmfw** – load firmware for Broadcom BCM2033 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/ubtbcmfw**N**.**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
```
