Hi! did you have any problems with the usb connection through the Mod 2? I have the same patchbay and even connecting the QC or other pedals directly to the Mod2 doesn’t work, let alone through another usb hub before that. That aside, you have an awesome pedalboard!
QC’s USB connection seems to be a bit fidgety. I’ve had some USB cables that just don’t work and using USB extensions doesn’t seem to be compatible with the Cortex Control App, even though the USB audio interface/connection works through the same connection, go figure.
At the beginning of my using it, I thought I had an issue with it, but it ended up being the cables I was using. As it turns out in this case, it makes difference which way the cable is plugged in. So in my case I had a usb-a to usb-c cable, where the usb-a connector was supposed to be plugged into the computer and the usb-c was supposed to be plugged into the device. Basically to connect a phone to a computer or something like that. Well I discovered that if you plug the usb-c into the computer and the usb-a into the MOD2, it wouldn’t work. My solution that has worked is I bought a pack of two sets of usb-a and usb-c adapters (4 total, 2 a>c and 2 c>a). You can kinda see in the one picture the adapter at the end of the cable plugged into the MOD2. Thanks for the compliment, and I hope that helps!
