"Doesnt work" is not very informative. Does anything work at all?

Can you pass enumeration of the mouse (read descriptors) ? Can you get raw report data from the mouse?

[Ejunior007]

yes, anything works. i connect the mouse via usb port or via mcu pins and nothing respond (the led is always off). in these code i use a callback function for every data (x,y) and will be displayed in PC via uart.

i use the A725 sensor.

The LED always off can mean that the device does not receive power from the USB host.

 Have you tried to connect a simple mouse instead of the sensor?
