This should happen automatically, but sometimes the Windows® driver does not recognize the tool correctly. To correct this, you have to check that the tool is listed under the Microchip node in the device manager in Windows. If your tool is not listed, try to find it under Unknown devices. If it is located there, try to reinstall the driver by double-clicking the tool, click the Driver tab, and choose Update Driver. Let Windows search for the driver. The driver should be reinstalled, and the tool should be displayed under Microchip. Now, the tool should be usable from Atmel Studio.
