This means that autosuspend is off.
Did you checked after rebooting?
Could you try cat /sys/bus/usb/devices/1-8/1-8*/bInterfaceClass ?
If it's not 0e, either that is not the webcam or it is a webcam that
uses a different protocol/driver.
If it is 0e,  there's a problem with the rule... in which file did you add it?
Cheers,

Luca
