I recently installed third-party drivers for the (Sony) PS3 controller on my friend's PC (Windows XP). I found out a few days later that his MP3 player (also Sony) is no longer recognized by Windows. He gets the "connect device" sound, and about 250ms later, the "disconnect device" sound.
I figured the controller driver took over the Walkman's device ID, so I went through the registry and
C:\Windows\inf removing all references to Sony's VID (
054C), but I haven't had any luck.
What would you do in this situation?
