Did you plug in both USB ends on the adapter? When I made my Blueretro the first test I did was in one of those adapters and the Blueretro could not even turn on due to lack of power until I plugged the second line in. Even though a single wired controller can work with only one USB connection.

Yes, both ports are plugged in. The blueretro is powered, i was even able to do a firmware update on it

Just tried it with an xbox controller, same issue. It connects but no response in game. Maybe an issue with my gamecube usb adapter? It's an aftermarket one

Also tried the blueretro adapter in a real gamecube and it works. So it doesn't work with the wii u usb adapter only, despite it working with wired controllers. Pretty weird issue

Over some time, I did some extensive testing for this type of thing. I did find a solution, I just needed the right device going in the right controller port. You can read about it here, hope it helps.
