I just found difference between SL1602 Firewire vs SL1602 USB.
SL1602 Firewire uses UC 1.7.6,
SL1602 USB uses UC 2.8.
UC 1.7.6 don't Recognize SL1602 USB.
Only UC2.8 works for USB version.
It is ok, but there is one problem.
UC 2.8 feature is less than UC 1.7.6. Channel name, color editing.. etc are impossible.
Higher version less feature. I don't understand that.
If you run UC 2.8's DEMO, there is StudioLive 32.4.2 AI, it works everything.
But StudioLive 16.0.2 don't works, even interface is different.
(StudioLive 16.0.2 USB's VSL on UC 2.8)
(StudioLive 32.4.2 DEMO;s VSL on UC 2.8)
There is no button for channel setting at SL1602.
I want UC 2.8's VSL for SL1602 USB works completely same as other Mixer's VSL.
