HD44870 LCD to USB

Hi guys, I'm rather new to building electronic circuits. But the project I have in mind requires a 20x4 LCD display being driven over USB by a computer.

Heres the display I would like to use.
CFAH2004K-TMI-JP, Parallel Character LCD 20x4, RoHS Compliant, White Edge LED Backlight, S

Basically, I'm looking for a controller that's pre-build and just needs soldering to the LCD. Any ideas?

Bump, any one? Please

You're looking for something that probably doesn't exist - USB isn't a trivial thing to use.

Yes, get an Arduino microcontroller board, around $30.

Arduino - ArduinoBoardDuemilanove

It has all the hardware required to interface your display to a PC. Your PC will see the board as a simple serial comm port. Your PC application program will send characters out the serial USB port. The program you write for the Arduino will convert these serial characters to either a 8 bit or 4 bit format to send to the display. The Arduino IDE software system has software functions already created to talk to these types of display controllers.
