Hola
Estoy haciendo un JoystickMouse con arduino micro y funciona perfectamente.
pero si enciendo el PC con el arduino previamente conectado, el JoystickMouse no funciona, para que funcione tengo que desconectar el cable usb del arduino y volver a conectarlo.
El codigo usado es el del ejemplo de arduino.
/*
JoystickMouseControl
Controls the mouse from a joystick on an Arduino Leonardo, Micro or Due.
Uses a pushbutton to turn on and off mouse control, and
a second pushbutton to click the left mouse button
Hardware:
* 2-axis joystick connected to pins A0 and A1
* pushbuttons connected to pin D2 and D3
The mouse movement is always relative. This sketch reads
two analog inputs that range from 0 to 1023 (or less on either end)
and translates them into ranges of -6 to 6.
The sketch assumes that the joystick resting values are around the
middle of the range, but that they vary within a threshold.
WARNING: When you use the Mouse.move() command, the Arduino takes
over your mouse! Make sure you have control before you use the command.
This sketch includes a pushbutton to toggle the mouse control state, so
you can turn on and off mouse control.

He probado en varios PCs y me pasa lo mismo.
He probado en android y no ocurre ese problema.
Alguna idea? ...
