Troubleshooting your connection
Start with the connection
- Open the guide for your exact board.
- Check that each USB cable carries data.
- Confirm the board appears in Windows Device Manager.
- Wait for Connected in Knife.Baby’s board card.
Single-PC mouse issues
Check the mouse is connected to the shield or board’s USB-A host port. For a Leonardo shield, check its power jumper against the manufacturer’s instructions. For the Feather RP2040 USB Host, repeat the BOOT/RESET sequence if flashing is not detected.
Dual-PC board issues
For a Leonardo, check TX → RX, RX → TX, GND → GND, and adapter signal compatibility. For a Due, check Programming → second PC and Native → gaming PC. Do not loop the board’s mouse-output connection back to the PC running Knife.Baby while Passthrough is enabled.
OBS / NDI discovery or stutter
Check DistroAV’s Main Output, private-network firewall permissions and Ethernet connections. Enter the gaming PC’s IP address manually if discovery fails. Lower OBS FPS until the stutter reading stays low.
Ask for help
Open a support ticket with your board model, setup mode, mouse model, Knife.Baby version, firmware version and exact error message. Include a clear photo of the wiring if relevant. Do not send passwords or license keys.
