Hi

I need to have 16 + 2 midi ports in one single USB connection

I try to made a configuration with IAD and 4 interfaces (two audio controls followed by midi stream each)

These are problem

1- Midi-ox seems that see them well, but naming of port is duplicated between 16 and 2 port group

2- SONAR 4 don't see the first device of group2 (because has the same name of first 16ch gruop)

3- In control panel / device I see a device with error code 10

If was possibile to add image I can show better the problem. I can attach also USB device descriptor dump if needed

thanks who want to help me

Paolo
