USB to Raspberry Pi Console Connection for Java Embedded Development

Just follow the hint that Wolf Paulus gives in his blog post (photo is from Wolf Paulus also)
For Java Embedded development, the easiest way I found (which I told Gary C. about recently) is to use an FTDI Breakout Board with a USB port.
Here are the steps:
1. Buy these parts: OSEPP FTDI Breakout Board $15.99 http://www.frys.com/product/6997547?site=sr:SEARCH:MAIN_RSLT_PG Set of Jumper Wires $12.99 http://www.frys.com/product/7367744?site=sr:SEARCH:MAIN_RSLT_PG SIIG 2 Amp/2 Port USB Adaptor http://www.frys.com/product/7182042?site=sr:SEARCH:MAIN_RSLT_PG Micro USB cable http://www.frys.com/product/6151789?site=sr:SEARCH:MAIN_RSLT_PG 2. Make sure the jumper on the FTDI Breakout is configured for 3.3 volts. 3. Use the jumper wires to make 2 connections from the FTDI Breakout Board to the RPi: From FTDI 3.3V TXD to (GPIO Pin 8) From FTDI 3.3V RXD to (GPIO Pin 10) See this Web reference: http://wolfpaulus.com/journal/embedded/raspberry_serial 4.Connect one end of a USB cable into the FTDI and the other end into the Windows/Mac/Linux PC. 5. Then use PuTTy or minicom on a Windows/Mac/Linux PC with a new connection to the right serial port (Ex. /dev/ttyUSB0 on a Linux PC or COM5/COM6/COM?? on Windows PC) using these serial connection settings 115200 bps 8-N-1. 6. Hit return a couple times to get the console prompt. Make sure the RPi is properly powered with it's AC adapter (not connected to a computer for power since only the AC adapter that comes with the RPi has enough current to drive it for this use).
Voilà! You have a USB connection to the RPi console to do your Java Embedded programming. Nifty, huh?
