Here's another one. After one bashed PC driver for a SIXAXIS to talk to, this is PS3-connect.de's zoople with his own version of Windows XP driver für den SIXAXIS controller. It's the same deal when it comes to results: the motion sensors won't work with this yet, and the drivers themselves aren't from Sony. Installation is almost straightforward - drivers to install, something to unpack, plug and play the PS3 controller. Here are the instructions, crudely interpreted from the Google translation:

* Install libusb-win32-filter-bin-0.1.10.1.exe, which comes in the zip file below.
* Unpack ps3sixaxis_en.exe
* Plug the SIXAXIS to the PC (via the USB cable), which should have come with your purchased PS3. If you don't have a PS3, what did you do, buy the SIXAXIS stand-alone?
* Run ps3sixaxis_en.exe once. (Nothing said about the boo-boos that would result if you run it twice)
* Push the PS button if the program doesn't "handshake" with the SIXAXIS (we think, based on our research, that's what it meant).

Finally, an indicator that this thing might work out in Mac OS X, too - if you execute under Boot Camp. Here's the download link for the drivers. no one tell Microsoft we're running their competitor's controller on the PC (eh, not that we don't do the same thing with the Wiimote, anyway).
