The problem seems to be that the device permissions are not being correctly set by udev when the board is plugged into the pc's usb connector. If I run the Arduino IDE as root, it lets me use the ISP R3 usb programmer board. Not convenient for sketchbook management! I can temporarily fix this prob…

Help fixing device permissions for A000092 usb programmer board, in Ubuntu
