Xadow upload sketch

Hello.

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?

Thanks,

Hello

What OS are you using?If it is Linux try the following solution

sudo usermod -a -G dialout Username

and restart the PC.

Thanks and Regards

Thanks kavi.

Yes, I’m using Linux.

My user is already in the dialout group.

But now, which board should I use to upload? Leonardo or Xadow?

Thanks,

Also, consider that I’m able to upload on different boards and on the old Xadow with the same IDE.

OK, SOLVED:

I had to remove Modem Manager

#apt-get remove modemmanager
