lsusb - Output of 'lsusb -v -d 18e3:9512'
************
Sometimes the webcam works on bootup (or a few mintues after), sometimes
it works immediately after I run lsusb, mostly it doesn't work at all.
Sometimes the laptop will be on for hours before the webcam spontaneouly
works. Usually within a couple of hours of working it will spontaneously
stop working.
My fear is that there is hardware problem - is it possible to determine
whether or not this is the case?
