Arduino Deuvilova ( :) USB not recognize by WinXP

I had one AtMega168 arduino board, but the usb cannot be recognized by the PC. But when i Plug in external power to it , the USB can be recognized.
After searching around, seem like this problem is due to the FT232RL chip.
The solution is to short Pin 25(TEST) and PIN 26(GND).

RS485 to RS232 converter

http://aquaticus.info/rs485_to_rs232

Popular chip MAX232 is used to convert RS232 signals from/to TTL level. MAX485 converts TTL level signals to RS485 standard. RTS line is used to change transmission mode of MAX485. RTS signal is first converted to TTL level by MAX232 then connected to DE and RE/ pins.
