Because i didn’t want to invest too much time into get the avrdude running i decided eventually to use the Atmel Studio with the AVRISP.Īs following i will explain you how to deal with Atmel Studio and the AVRISP mkII ISP programmer to transfer programs to the Arduinos flash. But everytime i’ve got the error message „avrdude: usbdev_open() did not find any usb device usb“. So i tried to transfer a small test program with help of the AVRISP and the arduino IDE to my Arduino. In my opinion a small, powerful and not really expensive device. This device has also a lot of other features. To save time and nerves, i decided to use the AVRISP mkII programmer – a device which is able to program AVR devices over the SPI interface. Finally after a lot of attempts the driver were successful installed, but evertime after i’ve connected the PC with the Arduino board (by micro USB cable), the virtual Arduino COM port appeared for a short moment in the hardware manager and after few seconds the COM port disappeares and shows instead an ‚unknown device‘. Then i have tried to install the Windows USB driver which are delivered with the arduino IDE. I installed the arduino IDE (currently 1.0.5) under Windows7 (64bit). Probably you have the same problem like me: Some days ago i have bought a tiny Arduino Micro board to play a little bit around with them.
