The trouble is that that there are two different arduino companies(arduino.org and arduino.cc) that are in a legal dispute over the rights to the trademark.

There is also a workaround for using the arduino.cc driver with your device. It is explained here: ArduinoISP driver no recognize the hardware · Issue #4120 · arduino/Arduino · GitHub
