locationID

hi.
we have been using your addon for a while now on OS X. it is just great :)
we use logitech c920 cams and we are able to control them successfully.

the problem is when using two or more c920.
when setting up two controllers via initWithVendorID then both controllers connect to the same camera.
when using initWithLocationID you need to feed it the correct usb location. i can get the cam's location with the OS X "system information" app. looks like this 0x00300000 / 1
but that is cumbersome and changes from computer to computer.

have you found a way to enumerate the available devices and make sure multiple controllers always pick a camera that does not yet have a controller associated with it?

thanks.
