Some months ago I bought some Xadow main board. I was able to upload sketches with Arduino 1.5 by following the instructions given in the Wiki. So far so good.
Recently I bought a couple of new main boards, but there is something strange: the board has now a different ID. It is recognized as Arduino Leonardo. But if I try to upload sketches as Leonardo Board I get an error:
avrdude: ser_open(): can’t open device “/dev/ttyACM0”: Device or resource busy
avrdude: ser_send(): write error: Bad file descriptor
Do you know why this happen? Why the ID of the board has been changed?
