BINGO!!!!!!!!!
It works! 
Thank you Frank for solving this mystery.  Well done!!!! I have been trying to
solve this for quite a while.
I changed the Register value, rebooted the machine and voilá! And it even
works while the notebook is connected through the huawei modem!
Please, publish the solution in the wiki.
This bug is dead, thanks to DL2ALF
