I have an arduino nano laying around, but it stopped working a while ago. I can't exactly remember what happened, but I think I hooked up too many LEDs...
Because it is quite expensive I want to look into the opportunities to fix it. When I connect it to my computer there is no port visible(macbook) and in vista it says "usb device not recognized". This makes me believe the FTDI chip is fried.
Is there a way I would be able to test the FTDI chip and is there a way to test the atmega168 chip, so when I am going to replace the FTDI chip I am sure it will work?
By the way the power LED is on and the reset LED blinks if I press the button.
Hi,
as a last test I would suggest you plug the nano into a linux-box and run the dmesg command in terminal after that.
The Linux USB-Subsystem usually prints a detailed error-message.
If you know someone with a hardware-programmer you can also try to upload some code with the programmer, so you can check wether the Atmega is still alive.
You need a pretty steady hand to replace the FTDI-Chip, good luck with that ...

Connecting the RX, TX, 5V and Ground does not enable me to upload programs... I've tested it with a Diecimila too, so I should connect an other cable somewhere?
