Programming with Arduino IDE a Cubecell?

Hi

Is there someone that succeeded already to upload a new program in a Cubecell 1/2AA. I’m killing my head trying to upload a code written in Arduino IDE. I have installed all libs in Arduino IDE, but upload at Cubecell always fails ! If I plug it in USB on computer I see the usual serial port shows up but Arduino IDE is unable to transfer on that port. If I hold the user button before plugging USB on board it shows up as in DFU mode in lsusb but then I can’t access it from Arduino IDE as it has no more any serial ports !
Any ideas what’s problem ?

Thanks
