Mouse doesn't work

Ensure all three USB cables are connected correctly — Left to Main PC, Middle to Second PC, Right to Mouse.
Verify your mouse is not on the incompatible list.
Try a different USB port on the Main PC.

MAKCU.exe won't detect device

Verify the CH343 driver is installed correctly.
Check that the COM port is set to a number below 10 in Device Manager.
Restart the MAKCU by unplugging and re-plugging the middle USB cable.

Cursor doesn't teleport during test

Ensure both the Left (Main PC) and Middle (Second PC) USB cables are connected.
Verify firmware was flashed successfully to both the Left and Right ports.
Check that the mouse is connected to the Right port.
