I've written a driver for "USBtiny LIRC compatible IR receiver and LCD controller" from http://www.xs4all.nl/~dicks/avr/usbtiny/index.html.
It have been tested on 1x16, 1x20, 2x16, 2x20, 2x24 & 4x20 HD44780 based LCD displays.
It requires libusbWIN32 (http://libusb-win32.sourceforge.net/)
This job have been done on V5.4.1 Beta (latest developpement release). Also based on LCD2USB code. Have been compiled on [MinGW+Eclipse] latest version; Binary dll and source code is included on irlcd.lcdsmartie.zip joined to this post.
