thanks a lot, I read only part 1 of this nuggets, missed somehow part 2 concerning control pipe....
I will go through this and let you know if I come to something. We are close to hire a person to do this job for us as we do not know the USB protocol and we do not have so much time to solve this issue....thanks a lot for the support, tomorrow I will go through the nuggets and try to use control pipe to control the instrument...
