ArduinoCommander - android application to manage arduino board

I am trying to connect using USB OTG cable converter on Samsung Galaxy S3.
My UNO is discovered in USB devices as /dev/bus/usb/002/003
I also have the Standard Firmata sketch installed
I tried every baud rate but it won’t connect.

Any ideas anyone?

I have the same problem, I connect it to my tablet and my arduino turns on but it wont show up on the USB devices tab.
How can I fix that?
