I'm trying to see the output of an accelerometer with Ubuntu (15.04), kernel 3.19.
The UART driver is `cp210x.ko`, and the chip of the accelerometer is MPU6050w.
So, when I plug the device, I have this:

```
$ lsusb
Bus 001 Device 024: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light

$ sudo dmesg -c
[45550.171578] usb 1-14.3: new full-speed USB device number 24 using xhci_hcd

[45550.279845] usb 1-14.3: cp210x converter now attached to ttyUSB0

$ lsmod | grep cp210
cp210x                 24576  1 
usbserial              49152  3 cp210x

```

The problem is when I want to read the output of `/dev/ttyUSB0`, there's nothing.
I have tried a lot of tools, cutecom, minicom, screen...
And no signs but the LED of the card which flash when I turn the card.

Here are others infos I have:

```
$ sudo lsusb -D /dev/ttyUSB0
Cannot open /dev/ttyUSB0

$ ls -l /dev/ttyUSB0
crw-rw-rw- 1 root dialout 188, 0 mai    4 10:57 /dev/ttyUSB0

$ stty -a -F /dev/ttyUSB0

```

Could someone help me to solve this? I've seen this [question](https://unix.stackexchange.com/questions/120992/why-does-cat-ttyusb0-not-produce-output) but no solution for me.
