Hello.

Sorry for the inconvenience you are experiencing with the IOIO.

Could you tell me what you are powering the IOIO with? Perhaps the IOIO is not getting enough power and is shutting down.

Definitely check the following page out:

Also, please give the board a good visual inspection with a magnifying glass if possible and look for damaged/missing components or any solder bridges and cold joints. Use the pictures on the SFE website as references.

Let me know what you find.

Hello TS-John, I tried to power by:
- 12V 2A power supply
- 5V power supply from SF (https://www.sparkfun.com/products/10804)

By visual check all seems to be ok

Also when I connect to the computer do the same, here is my dmesg output:
