Mr. Harbaum recently anounced "Complete and assembled LCD2USB compatible 
devices are available from http://www.lcdmodkit.com 
<http://www.lcdmodkit.com/lcd.html>." See his page for more info.

I just want to mention that the original lcd2usb has software adjustable 
contrast as well. I have no problem with the difference as long as the 
protocol implemented in hd44780-lcd2usb does not need to be changed and 
the firmware can cope with the hd44780 initialization sequence sent to it.
