Firmware

A firmware update is available for this card's Bluetooth controller. Unfortunately, the firmware update can only be applied under Windows 2000 and above. Other operating systems are not supported to allow the firmware update to run.

An unofficial work-around for Linux exists, but this has not been confirmed to work and may potentially brick the Bluetooth controller. The work-around is simple. By using the firmware .dfu file provided by the Windows utility and extracting it with cabextract, the firmware image itself should be able to be flashed by the btdfu tool in Linux.

Linux driver

This card will work with the standard Linux Bluetooth drivers.

This device is implemented as a USB device, you might be able to enable or disable it by using Fn-F5.
