I just got an XBox 360 controller for the PC ("XBox 360 Wireless Controller
via Play & Charge Kit") and the driver from
http://www.microsoft.com/hardware/download/DownloadResult.aspx?category=Gaming&type=Gaming&name=JR9-00001&os=XP_SP2&lang=en
but it's still not showing in the Game Controllers control panel, nor being
recognized by my games. I've tried uninstalling/reinstalling the drivers
with no luck. I press the "X" button and the ring flashes green: Three
fast, then 12 slow. Ports are OK, no other USB devices connected.

Anything else to try, and are the flashes an error code?
