SteelSeries released a new version of the SteelSeries Engine (v2.1.745) which updated the firmware of the Diablo III Headset and the Diablo III Mouse. It was released on January 20, 2012.
The new SteelSeries Engine update contains Diablo III Mouse firmware version 259, and Diablo III Headset firmware version 272. I updated both with no problems.
The firmware is compatible with Win 2000, Win XP, Win Vista, Win 7 (32/64 bit) or Mac OS X (10.6+).
Download the Mac or PC version here. Before installing, go to START. Choose Control Panels. Then Uninstall a Program. Search for the SteelSeries Engine and select uninstall. During the uninstall process you will be asked if you wish to keep the settings. Click the checkmark to keep them. After uninstalling, launch the SteelSeries Engine .exe file. It will take a while to install and to program the devices with the new firmware.
