I hope you can read English ... my German writing is very bad ... !!

I have had the same problem.
An application with more than 10 identical USB-devices.

Normally, you could use the serial number of a device, but sometimes these are all similar.

I used the loaction of a device, on arrival.
Each USB device has a unique location: hub, port.

With this location, you can very reliable distinguish between devices !!
Two devices will NEVER have the same location.

Registry-entry: "SYSTEM\CurrentControlSet\Enum\USB\" ; LocationInformation.

You will need some extra code to use this method.

Good luck, Alfred.
