Why Vendor ID & Product ID of Arduino Micro (USB Device) are different in Linux and Windows?

I'm developing a software that comunicate with an Arduino Micro using Qt for C++.

I'm using QSerialPortInfo to show some information of my Arduino Micro with this method:

for (QSerialPortInfo info : QSerialPortInfo::availablePorts())
{
   qDebug() << "Port Name   :" << info.portName();
   qDebug() << "Description :" << info.description();
   qDebug() << "Manufacturer:" << info.manufacturer();
   qDebug() << "Vendor ID   :" << info.vendorIdentifier();
   qDebug() << "Product ID  :" << info.productIdentifier();
}

In Windows 10 this is the result:

Port Name : "COM4" Description : "Arduino Micro" Manufacturer: "Arduino LLC (www.arduino.cc)" Vendor ID : 9025 Product ID : 32823

And in Ubuntu 15:

Port Name : "ttyACM0" Description : "Arduino Micro" Manufacturer: "Arduino LLC" Vendor ID : 5549 Product ID : 1908

Why Vendor & Manufacter are differents ? I think the IDs are about the device so must still be the same, platform independent .. I'm wrong ?

If I want to check if a device is my device how can I do it ? I wanted to do a simple check with a Vendor & Product ID

UPDATE:

I forget to tell that I'm using Ubuntu with a Virtual Machine on Windows10 with VMWare (if it can change something)

Are you possibly getting device driver information? – NathanOliver
@NathanOliver which kind of driver information ? In windows I have installed the drivers with the arduino IDE, in Ubuntu the same. – Simone Pessotto

Your virtual machine has a virtual serial port, and the virtual serial port has a virtual vendor ID. 5549 is hex 15AD, which is VMWare,Inc.
