A side question on this topic: I was messing around with PS3 and XBOX360 controllers a while ago in an attempt to get one working in Windows (I gave up in the end and got a cheapo dualshockalike which does the job nicely.) What doesn't seem to be mentioned anywhere is that the standard wireless 360 pad is recognised by Windows when attached via the play&charge lead.
Sadly, for me at least, recognition is as far as it goes. Windows recognises it, downloads drivers, and that's it. It's not recognised in the joystick cpl or anywhere else - the only way you can tell it's there is to go to Device Manager and check what's attached to the USBs.
Anyone have any insight into this? (Vista x64, if that makes any diference ^^)
