I got two 13,3" Penabled digitizers a while back and I decided to solder leads to one of them and try to connect it.
I knew it is a USB digitizer so I looked for the pinout on the wiki and connected it according to it.
After I connected everything and nothing worked I started to think if the digitizer was defective or if I had to connect some additional pins.
The one error that pops up in the syslog (Linux) says "unable to enumerate USB device".
So what did I do wrong? Turns out the data pins are swapped! (the wiki says Pin3=D- and Pin4=D+ but this is wrong. at least for my digitizer)
After swapping the two lines, Linux happily detected the digitizer and everything was working as expected. great!
I connected it using the following scheme:
Pin 1 & 2: GND
Pin 3: Data +
Pin 4: Data -
Pin 13: 3,3V
Pin 14: GND
Also I noticed that the tablet resets if I pull pin 11 to GND (and only connects back to the PC if pulled to 3,3V or replugging the digitizer)
All other pins had 0,0V (no Pen-is-on-digitizer-LED

If you have any more questions or things I could try out just ask. (It's not a huge deal if I kill it as I have a second one and one did cost 3€ so I can tinker with it a bit more than with usual tablets
