I have problem with Attiny817 Xplained mini board. I used this board few months ago with Atmel Studio 7.0.1645 and it works fine. Now I installed Atmel Studio 7.0.1931 and launch and connect the board to the computer but it now installed as Atmel USB Devices Atmega 32U4. I don't have installed have mEDBG and COM port. So installed board isn't useful in Atmel Studio. Why this board now is installed as USB Device not mEDBG device.
