Arduino USB not found on RPi 2

Hi guys,

What i'm trying to do is connecting an Arduino to my RPi 2 through USB serial port (without USB Hub).
My RPi 2 is running Raspbian Jessie.

The arduino version that I've used is both Arduino Uno and Arduino Nano. With bot i'm having issue finding the serial port.
NB. I'm not using the Arduino IDE. Do I need it to make it works? maybe any driver missing?


Instead the "dmesg" command output this:

Code: Select all

[284803.322999] usb 1-1.2: New USB device found, idVendor=2341, idProduct=0001
[284803.323032] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=220
[284803.323048] usb 1-1.2: Product: Arduino Uno
[284803.323065] usb 1-1.2: Manufacturer: Arduino (www.arduino.cc)
[284803.323081] usb 1-1.2: SerialNumber: 752303137333514092E1
And also the lsusb seems to detect it:

Code: Select all

Bus 001 Device 007: ID 2341:0001 Arduino SA Uno (CDC ACM)
But the serial port of Arduino is not listed when executing "ls /dev/tty*" command in console, that returns:

Code: Select all

/dev/tty    /dev/tty19  /dev/tty3   /dev/tty40  /dev/tty51  /dev/tty62
/dev/tty0   /dev/tty2   /dev/tty30  /dev/tty41  /dev/tty52  /dev/tty63

/dev/tty14  /dev/tty25  /dev/tty36  /dev/tty47  /dev/tty58
/dev/tty15  /dev/tty26  /dev/tty37  /dev/tty48  /dev/tty59
/dev/tty16  /dev/tty27  /dev/tty38  /dev/tty49  /dev/tty6
/dev/tty17  /dev/tty28  /dev/tty39  /dev/tty5   /dev/tty60
/dev/tty18  /dev/tty29  /dev/tty4   /dev/tty50  /dev/tty61
I wonder if someone have ever met this kind of issue..
What should I do? I've not installed the Arduino IDE yet, because what i'm trying to develop shouldn't require it.

When I plug my Uno into a RPI2B running Jessie I get

may I need to restart the RPi? or apt-get install arduino ?

Don't know. Try a reboot.
