libusb 1 is the current new version of libusb and has some features 
we prefer to use, like asynchronous USB Interrupt reception. So libusb1

Is the zoom motor driven?

We had this query before, but so far were not able to make out if that
is possible or not.

None of the exposed property values seem to suggest the possibility,
While there always is the possibility of a yet unknown vendor method
to set it, it seems unlikely.
