Electronic – FTDI chip based custom board. Driver not working

ftdi

I designed a board containing a USB to UART bridge in order to program a ATmega microcontroller. I copied the schematic of this breakout board from Sparkfun

https://www.sparkfun.com/products/9716

This is my schematic:

enter image description here

I install FTDI drivers from this link:

http://www.ftdichip.com/Drivers/VCP.htm

in "windows – setup executable". It doesn't work. My computer doesn't recognize it. I have windows 8.1 and I think it could be related. I disabled device driver signatures.

I don't know what to do now. I don't think it's related with my schematic, but I can't solve this problem.

Any idea?

Thank you.

If by "my computer doesnt recognize it" you mean you can't run the exe to install the drivers, you probably have a corrupt download. Download the file again and see if it works.

If you mean the installer worked just fine, but the drivers aren't working properly, then you either hooked it up wrong, have a defective FTDI chip, or have a counterfit chip.
