Also known (in IBM literature) as....
- Bluetooth Daughter Card

- BDC board
A firmware update is available for this adapter from IBM.
The updated firmware is version 310, and is available here
This firmware update can unfortunately only be applied from Windows.
In theory an update for Linux exists; the BTDFU update utility that can be found on the pages of Marcel Holtmann, the current Linux BlueZ stack maintainer, which can be found here. You need to get the original IBM update file and extract the file with the extension "dfu" from it using cabextract. Using the btdfu tool and this file it should be possible to update the firmware. This procedure has not yet been confirmed.
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.
