I’m trying to install the BCF2000 but I have no success and now I don’t have any more ideas. Please help me!

I powered the BCF and connected it to USB. Windows say that it have found new hardware and installed it correctly. But BC manager says that there are no controllers connected.
I have tried to change USB port and cable with no success.
I have installed Behringers MIDI drivers.
I have no more ideas so please tell me what I have missed. Thanks for your help.
