New hardware VID_04E6_PID_80000001?

When I restart my computer, I get the message that new hardware found VID_03E6_PID_80000001. I have no idea what this hardware is and therefore I cannot load any drivers for it. Can anyone help? In my registry it was labelled as an SCM pport cf adapter, whatever that is. I have not added new hardware to my computer other than a cd-rw drive several months ago (my previous cd-rw failed and had to be replaced). Thanks. MMN.
