Help to configure my LCD HD44780 connected via USB (lcd2usb) to Raspberry Pi 2 running Rasplex 1.6.2

Hi,
I´m having problems to configure my LCD with Rasplex 1.6.2 in my R

I´m using a Raspberry Pi 2 running:
RasPlex (official) Version: 1.6.2.123-e23a7eef
RasPlex git: 7580777a4bed0010d190ac3f04ebc686bf28a414

connected to LCD driver “hd44780” with lcd2usb.

I´m getting the Hello message “Welcome to Rasplex” when I boot the Pi but after that, LCD doesn´t display anything on it.

I´ve enabled also the LCD configuration in the two places (Settings and System Settings) of the GUI and this is the configuration made in the LCDd.conf file:

# The following drivers are supported:

KeyMatrix_4_4=Escape

I´ve restarted after configure all the settings several times but… after the message of Welcome to Rasplex nothing more is showed.
