Help with QExtSerialPort libary[Qt4]

[ZenT]

Hello everyone!

i'm actually stuck pretty much for the last hours(!) make my application work but i still had no luck...
I've looked everywhere on the web and i'm very frustrated of this.
Here's the problem:

I need to develop a software that detects when a USB drive is plugged in the a computer, get it's friendly name & drive letter
and copy some data from a folder which is pointed by the volume label. The main problem is that i tried all libraries i could find
including qt's 2 other ones, but i had no luck. I found out that QExtSerialPort actually fit for my needs so i tried to build it
and got the .dll & .a files. I compile my project, everything ok, but when i call the getPorts() function the QList is not filled.
It's like i never called the function. I checked everything that could cause this but i cannot find it...
So the main thing is: I call getPorts() and i get no ports at all, even though i have a USB drive connected to my computer along
with a mouse.

What could be the cause for a static function not working well?
I beg for your help cause i'm really confused... :S
