arduino_101: USB device is not listed after flashing with a Zephyr sample

[dhavalpanchalispl]

OS: Ubuntu 16.04
Device: Arduino 101 (Intel Curie Board)
Zephyr SDK: 0.9.1

I have flashed both ARC and X86 cores of Ardunio 101 board as mentioned in this sensor example,
https://www.zephyrproject.org/doc/samples/sensor/bmm150/README.html
And it successfully uploaded image to Arduino 101 device. Here is the output for "make BOARD=arduino_101_sss flash",

But I can not find any USB device listed in my Ubuntu system. To see output logs of board I tried command, sudo picocom /dev/ttyUSB0. But there is no ttyUSB0 device. Also cutecom (sudo apt-get install cutecom) does not show any USB device after flashing.

Output of this command to check connected tty devices: "dmesg | grep tty",
[ 0.000000] console [tty0] enabled
[ 0.819096] 00:02: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A

I connected Arduino 101 device using USB power cable. I have not used JTAG debugger. Is it necessary to use JTAG debugger if I just want to see execution logs of my program? I want to see those sensor values in console as mentioned in this example, https://www.zephyrproject.org/doc/samples/sensor/bmm150/README.html. But I could not see because USB device does not show.

My issue is similar to this, https://lists.zephyrproject.org/pipermail/zephyr-users/2016-June/000436.html

Hi,

if you build the sample with default settings then you need a additional TTL-to-USB adapter. Required Hardware and Software: "If you wish to grab any data off the serial port, you will need a TTL-to-USB adapter".

as mentioned by @jfischer-phytec-iot , you need a dedicated cable for serial, Arduino 101 does not send serial output over the usb cable connected to power the device and flash it.
