I have an Atmel-ICE Programmer and I've some trouble to use it with the Arduino IDE.
I've installed the driver of the Atmel-ICE, plugged it to the ISP header of my Arduino Uno board (my board is aslo supplied). The green led on my ICE indicate that the device is correctly powered on.
However, when I try to upload a sketch (a basic on, like "blink") I got an error :
avrdude: usbdev_open(): did not find any USB device "usb"
I've tried to send the sketch by clicking "upload with programmer" but it doesnt work.
The default programmer type is AVRISPmkII but it doesn't work either with USBTinyUSB choice...
The ATMEL AVRISPmkII is no longer available. So I purchased an ICE programmer. I have been unable to get it to work on Mac OS X 10.10 and Arduino IDE 1.6.4
