 ### Features
 
-### QC Trigger
-QC trigger is an experimental feature. Since QC trigger uses same lines as USB data, those function co-exist pretty bad together. Due to lack of design schematics and documentaion it is diffecult to implement it properly. When QC is activated __no other__ USB operation is possible, __including firmware download__! It also affects system message output to `Serial` line which migh result in UI slownes or freezes.
