Cubase 6 Artist Control Continuous Disconnect

Cubase
1

Hello,
My artist control connects perfectly with cubase 6.0.7 but auto disconnects after just about 30sec!
Things l have done:

  1. Read the EuCon adapter manual
  2. Reinstalled everything … cubase, EuCon V2.5.7 Eucon Adapter 6.1.0.175
  3. Disconnected my adsl ( internet )
  4. Tested with my Protools HD - They sync alright


    I can’t mix without my hardware controller… Need some help!Thanks.
