Thank you all for your tips.

I discovered the problem is caused by the software. I've downloaded other 
software and the serial ports are detected immediately even when I unplug 
the dongle.

But that's just a solution for me, cause in fact I make the program for 
other, unknown people and when they don't use the correct software they may 
have the same problems and blame it to my program.

So the idea to start a thread to detect the comm-ports does not seem so bad 
to me.
I'll think about it.

Thanks and regards,


Anton
