I have an nlited version of xp2, without the usb audio support. I bought a webcam with inner microphone,i install it but i can use only the cam for video, not the include microphone, because there is a driver error (deleted usb audio xp support. There is a way to install usb audio xp support without reinstall another version of xp? Maybe registering some files extracted from cabs? Thank you in advance, 3gonus
