I am trying to program a SAMD21 Mini Breakout board from Arduino IDE (1.8.1), running on CentOS6 Linux, I get the following error: “No device found on ttyS0”.
When I push the upload button, the sketch is compiles and the log window shows:
Sketch uses 9528 bytes (3%) of program storage space. Maximum is 262144 bytes.
Forcing reset using 1200bps open/close on port /dev/ttyS0

The board is connected by a USB cable, with which I have programmed other platforms successfully. I can change from normal mode to bootloader mode by double clicking the reset button, which is shown by the LEDs accordingly, but the problem is the same in bootloader mode.
This is the output of an “lsusb”:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 002 Device 037: ID 1b4f:8d21
I think that the last line, which corresponds to my board, should mention a name. Apart from that, I would expect that a new terminal like /dev/ttyACM0 would be created when I plug-in the device (like it is the case with Arduino Due, for example), but no terminal is being created.
When I connect to an Arduino Due, “dmesg” shows:
usb 2-1.7: new full speed USB device number 38 using ehci_hcd
usb 2-1.7: New USB device found, idVendor=2341, idProduct=003d

In contrast, when I connect my SAMD21 Mini Breakout, “dmesg” shows only:
usb 2-1.7: new full speed USB device number 39 using ehci_hcd
usb 2-1.7: New USB device found, idVendor=1b4f, idProduct=8d21

It seems that the CDC driver is not activated, although the hardware setup guide (https://learn.sparkfun.com/tutorials/sa … ware-setup) says, that no driver installation / setup is required on Linux platforms.
Any suggestions?
