View Full Version : "Device node not found" on a Linux machine

01-13-2013, 04:35 AM
I am working to create a USB Keyboard of my own design to go in a custom desk I am building. I have written the code and it compiles fine but when I go to upload it to my Teensy++ 2.0 I get an error code and it tells me to hit the RESET button. I can upload the "blink" sketch just fine.
I am running this on an Ubuntu 11.10 machine in the Arduino 1.0.2 IDE.
I am using a Teensy++ 2.0 board and have all my buttons wired to pins 0 through 27 at the moment. each pin is initialized with the internal pull-up resister active and then the the button is pushed it goes to low.
each button is wired to it's pin and to ground.
I can't seem to get the source code to upload but anyone who would like to see it is welcome to drop me their email and I will send it along.

The exact error code is the one mentioned above. it simply says "device node not found" then says "Please press the RESET BUTTON on your Teensy to upload your sketch. Auto-reboot only works if the Teensy is running a previous sketch."

Does anyone know what this error code means and how to fix it??
