Depends on your USB Output Patching. If you’re feeding your DAW from post gain, its pretty clear that anything else (EQ, compressor, volume) does not affect recording. That’s exactly what I (personally) want to have during live recording, to obtain a clean signal for later mixdown inside the DAW.
If you indeed want to record post fader, you’ll need to set your global direct out source to post fader. Sadly you do not find this setting in the USB Output Patch, but on the channel routing screen (Select any channel and press the routing button, see chapter 8.7 Channel Routing).
