Output level difference between USB5/6 and USB3/4

I tried to use some VST plugins in DAW in real time with AxeFx3 as interface and noticed that dry signal level (USB5/6) is lower than with other interface.
I created a small preset in AxeFx3 that has only Input 1-> Output2 blocks to send same 'clean' signal to USB 3/4 to DAW and this signal is 9db higher then USB 5/6.
Is any reason for this difference in USB output levels ?
I'm using firmware 19.01

The difference is not in the USB channels. The difference is that the Out 2 (and Out 1) blocks in the grid boost the signal level. You'll have to trim some off of that level if you want unity gain to come back in via USB.
 
This ↑. The OUT 1 and OUT 2 blocks boost the signal level by 18 dB to provide a hotter line level output range. Drop your OUT 2 block level by 18 dB to get the same level as the DI from USP Inputs 5 or 6.
