Gamecube adapter not working with latest version of haybox device

[garciaErick]

Expected behavior: Connect haybox device to a valid gc adapter and be able to play on PC Slippi with this adapter.

Actual behavior: Box device only works via usb mode, on gamecube adapter it does not work

Troubleshooting steps:

• Updated to latest version of haybox firmware
• Confirmed device is usable (played tekken, melee with usb connection)
• Bought mayflash adapter (its V07)

Before you go on and explain why I should use USB connection, please focus on the conversation. I have my use case and my reasons, I want to ensure this feature does work and want to root cause why it is not working for me.
