getInfo() method return USB interface number

[ben-qnimble]

It would be helpful for the getInfo() function to return the InterfaceNumber along with the VID / PID of a USB Serial (CDC) device. When a composite USB device is connected, they can have multiple serial ports connected, all with the same PID / VID. The interfaceNumber is how the different ports can be distinguished so it would be helpful to identify (and filter) based on this. Additionally, it would be nice to add interfaceNumber to the SerialPortFilter dictionary so serial ports can be filtered by this as well.

Thanks, that's a really good idea. No promises when we can implement it but we'll keep it in mind as we look at other related improvements.
