Yes that was one of the first things I did! (well thanks anyway...
Then I tried another identical diecimil and it worked!
So now I am looking for cheep supply's of ft232rl chips near Belgium, and a small soldering iron (--)^
maybe someone know a fail safe way of testing fr232rl chips!
Windows makes an interesting sound when you plug and unplug USB devices... if it is recognized, it makes a nice sound, if it is not recognized, makes a different sound and you can click on the small USB symbol that appears in the lower right portion of the screen to install drivers, etc. We saw a picture of an Arduino board that lacked one of the electrolytic capacitors, in this same forum, so maybe the FTDI chip has some pins soldered incorrectly... you may try pressing it a little bit and plug the Arduino and see if it is recognized by the OS.
Great idea I have a multimeter so could test the contacts on the chip, will have to get some smaller probes smd stuff sure is small, it doesn't really look like that is the problem but you never know till you test!
Pushing a little on the ft232rl didn't so far bring any results!
I think I will try some of the tools on Utilities - FTDI and see if I can get anywhere...
Thanks you have given me a little hope
I've plugged and unplugges Arduino's at least a thousand times and that has never happened... I would say either the board is defective or the chip is not burned. Put an ohmmeter across the PTC fuse- the flat thing with gold pins.
The is power going to the diecimila and even a simple blinking led program running fine! (it works on batteries or usb no problem), I did check the PTC fuse and it seems to be fine only about 0.5 ohm across which is the same on the working one. but it still does not appear if I plug it in to the USB port, and as soon as I plug in the other working diecimila it shows up.
Anyway I don't see how it could be a power fault if there is power going the ATmega168. e.g. the program is running...
The soldering on the usb connection do look a little over done or something, but the does not seem to be any effect on the connections themselves, see below:
I do still hope it is not a hardware problem, but am getting a little pessimistic
