Bc2000 (for the BCF2000 & BCR2000)

hi. recently i have purchased BCF 2000 ( behringer) as a controller for 
my DAW cubase sx3. i have hooked it up in my cubase in mcc mode under 
mackie emulation in usb . i am now able to use it as a controller for 
my cubase mixer for audio parameters for volume and panning and also 
for playing recording etc etc. but i am not able to control vsti/midi 
tracks parameters with it ( moving the faders in the midi track in 
mixer does not change the volume and panning of the midi in mcc). can 
some one tell me please how to do it? . does it have to be in mcc mode 
itself to control vsti/vst synth/ vst fx ? . what are the other 
configuration i need to do in cubase to control vsti .i really dunno 
whether i have configured the hardware correctly coz this is the first 
musical hardware i have got. can some one help me out please. the 
manual is of no help as it sounds so technical........
