As it looks from outside the dongle is not powered up.

Yes. I have tried with a Linksys USB wifi adapter and that worked (a
different driver is used though).
I have tried with VirtualBox and none of the Wifi USB adapters worked.
I got the error "uhub0: device problem, disabling port 1".
The adapters normally work fine (tried both of them under Linux in a
VBox and they worked fine).

Did not work, same problem...
