Game Input MultipleXer

Hi,
My specs are:
DIY USB adapter
USB to serial adapter: Módulo CP2102 convertidor USB 2.0 a RS232 UART TTL
AVR USB board: LEONARDO R3 Atmega32u4
Firmware (EMUG29PS4/atmega32u4.hex)
the console: ps4
the controller: g25
pc: windows 7 x32

Problem: I followed your tutorial with success till I tried to flash my arduino LEONARDO with the Arduino Builder tool. Before that my LEONARDO was showing up in WINDOWS>devices>com ports. But when I tried this:
Click on "Load Sketch / HEX", and select the desired atmega32u4.hex firmware.
Click on "Board Type" and select "Arduino Leonardo".
Click on the COM port that matches the "Silicon Labs CP210x ... (COMX)" COM port in the device manager (or whatever the name of your USB to UART board is). This is a trick to make the Arduino Builder tool look for a new COM port.
The following message should appear: "Forcing reset using 1200bps open/close on COMX...".
...I DID NOT the following:
Quickly unplug/replug the atmega32u4 board, or connect RST to GND twice.
Now my LEONARDO dows not show up in WINDOWS>devices>com ports. So it is not recognized too by gimx.
It was really late yesterday night, so I may have also made another mistake since i selected in "board Type" arduino "uno" instead of "leonardo". But I can´t really confirm this, maybe even did not happen.
So, I would really need some help since I am stuck. I have no clue where to go.
I think it is a must that my Leonardo is seen in WINDOWS>devices>com ports, right?
Any help is appreciated!

Hi,
This is as expected, the GIMX firmware changes the configuration of the USB port.
The USB port is inactive until the gimx software sends the appropriate start command.
The PS4 will recognize the Arduino as a G29, not as an Arduino.

Hi Matlo,
Thx for quick replay!
I connect everything and when I press the check button I get:
I pressed the start button and I got an error. So I decided to invert the tx/rx pins.
After that I pressed the start button and I got:
Then I pressed the PS button at the Dualshock 4 (connected to the pc) and the ps4 presents the login screen.
But there it ends...my G25 does not react at all.
Could you help me out what to check?

Please generate a log file.

And press the PS button while the log file is being generated.

Hi Matlo,
This is the log before I touch ps4 button in remote http://pastebin.com/4M03XDvP
And after I touch ps4 button in remote http://pastebin.com/5txXTfAQ

I can't see the PS button being pressed in the log.

I think tis is what you mean:http://pastebin.com/jmrcRB7E
