Hi I'm new to Arduino and seem to have fallen at the first hurdle. I can't get Windows (XP) to find the Arduino Duemilanove. The USB cable is good, I've tried it on two USB ports and still it won't find it.
The greed LED is lit and the LED marked L is flashing what appears to be 3 times.
I've tried to add the hardware manually but I can't get it to work even when I point it at the drivers.
I'd be greatful for any help you can give.
Oh and I have searched the site for help but couldn't find anything that seems to fit.
Go into computer management in control panel and click on device manager. Check to see if there are any unknown devices (ones with exclamation marks. If not then under serial/COM ports (or whatever it is) there should be a virtual serial port (if the drivers have worked).
There should be something in there that will be it. If you can't find anything then the FTDI chip may be damaged on the arduino board. Have you tried using a different USB cable?
I've tracked the problem down to the PC, it recognises other new hardware but won't recognise the Arduino. I'll use my home PC instead but if anyone has any ideas on how I can get it to work on my works laptop, I'd be grateful.
As mowcius said check your COM Ports, I had a very simular problem, the hardware device was not recongized until i had installed the drivers and reset the computer.
Also in the serial monitor window how many com ports do you have shown?
Do you have a 7 or 8? thats normally an indication that its there! Mines COM11.
Also depending on what libraries your using you need to know its serial port reference rather than the com port number.

Yes but presumably something comes up in device manager?

On laptops you often have less com ports anywaw. My normal PC only has 2 standard com ports. it has about 20 ish now due to all the virtual bluetooth com ports I have and my arduino virtual ports.
Thanks for the help.
I watched the drivers page update as I plugged in the Arduino. Up came COM8, it never recognised new H/W but the FTTI drivers were the ones it was using. So I guess my attempt to install them manually worked, even though at the time it didn`t look like it was accepting them.
