unkown device error with atsam3x8e native usb port

Hi,
In my project i have problem with native port detection in atsam3x8e, controller is working good in all other functions, when i connect my device through usb, its showing unknown device in device manager. Please do help me find a solution.

What code runs on that SAM? The processor alone (without code on it) does not provide any USB information to a connected PC so it has no possibility to find a driver for that device.

How did you upload? What board are we talking about? What IDE did you use?
