Where is the serial no. on the legria hf s20 - Canon FS200 Flash Media Camcorder

Have you considered looking in the manual ?

Nice Cam. USB 3.0 works best for this cam as it has a really high data rate. USB 2.0 will work, 1.0, will be poor. Start by downloading the software under product support.: Then it wall take you through it step by step.
