Gamo2 Faucetwo
From Rhythm Cons Wiki
This page lists troubleshooting and known issues with the Gamo2 Faucetwo controllers.
Please note that issues are user reported and not independently verified.
My knobs aren't responding at all
Try holding Start, BT-A, BT-B, BT-C, BT-D, FX-L, and FX-R for 10 seconds. This will swap between encoder and potentiometer mode.
Mode 2 and HID Mode Issues
It is reported that Mode 2 and HID mode do not work with USB 2.0 ports and require a USB 3.0 port.
Chord Splitting
It is reported that when all 4 BT buttons are pressed, the controller will chord split, resulting in delayed reports back to the game and up to 4ms of error.
My Lower Knob / Encoder Bracket Cracked!
