I'm testing a Teensy3.1 with the latest version of the UFTF Library and an iTeadStudio ITDB02-5.0 . I'm using the example provided in the library, with some Serial.println()s thrown in to see where I am.

Code:
// UTFT_Demo_800x480 (C)2014 Henning Karlsen
// web: http://www.henningkarlsen.com/electronics
//
// This program is a demo of how to use most of the functions
// of the library with a supported display modules.
//
// This demo was made for modules with a screen resolution 
// of 800x480 pixels.
//
// This program requires the UTFT library.
//

#include <UTFT.h>

// Declare which fonts we will be using
extern uint8_t SmallFont[];
const long baudRate = 115200;

// Set the pins to the correct ones for your development shield
// ------------------------------------------------------------
// Standard Arduino Mega/Due shield            : <display model>,38,39,40,41
// CTE TFT LCD/SD Shield for Arduino Due       : <display model>,25,26,27,28
// Teensy 3.x TFT Test Board                   : <display model>,23,22, 3, 4
// ElecHouse TFT LCD/SD Shield for Arduino Due : <display model>,22,23,31,33
//
// Remember to change the model parameter to suit your display module!
UTFT myGLCD(ITDB50,23,22, 3, 4); //Teensy3.1

The code compiles, but just before the Teensy Loader starts up, I get an error message "device node not found", and then the upload begins and completes. I'm currently using Teensyduino version 1.18 on a Debian 7.5 system.

Here's the stderr.txt as well
