Hi to all at arduino
just wondering if any one can help.
i have an uno r3 and a nano pro.
the uno works great no probs, connects, uploads. really happy with it.
but when i plug the nano in to xp sp2 pc via usb, it finds new hardware but wont install the drivers. i cant find these usb 2.0-serial drivers anywhere. iv tried re-installing the ftdi drivers from arduino site but the comm port still does not show up in the ide and i still have usb 2.0-serial flagged up in device manager.
again, if any ones got the answer please help.
many thanks
