Hi GWater, thank for the reply, see the output
$ dmesg | grep sn9c20x [ 244.453421] sn9c20x: SN9C20X USB 2.0 Webcam - 0C45:6270 plugged-in.

I typed the command, as Olstad suggested, but unfortunately the result was the same as my original post. Do you think a strace would be useful ? Thanks for your time and assistance.
