# apt-get source lcdproc
# lcdproc-0.5.3
# dpkg-buildpackage -rfakeroot
# dpkg -i ../lcdproc_0.5.3-0ubuntu1_amd64.deb
# strings /usr/lib/lcdproc/hd44780.so | grep lcd2usb

You have to start LCDproc as SU.

like my post LCDproc shipped with karmic didn't have support for lcd2usb in hd44780, sure there is some missing file during the compilation

try to check
# strings /usr/lib/lcdproc/hd44780.so | grep lcd2usb

kali is correct.

the lcdproc shipped with ububtu 9.10 does not have lcd2usb support.

to obtain full functionality I recompiled lcdproc from source,as indicated by him.

[Duststorm (duststorm-design)]

The source files are there but they are not built I think
make from source by specifying to build all drivers

./configure --enable-drivers=all
make
sudo make install

Maybe the .deb package could be remade with the --enable-drivers=all parameter

For information, look here: http://lcdproc.sourceforge.net/docs/current-user.html#hd44780-howto

"Compiling

Make sure that the HD44780 files are built when you run ./configure. This can be done by specifying --enable-drivers=all or by including hd44780 in the list of enabled drivers (e.g. --enable-drivers=hd44780). "

lucid build have the same bug

[Petr Jac (petr-jac)]

For compilation is required pkg-config and libusb-dev. Then configure, make ....
Maybe it will help somebody ...

This IMO doesn't apply to any lcdproc versions in Ubuntu anymore. Karmic is not supported anymore.
