I am having some issues with three Arduino Nano v3.0,
Two of the Nano's have the error "USB devise not recognised" when it is plugged into the computer
and the other one does not respond (it appears to be connected in hardware manager) however, i get the error
"Problem uploading to board. See http://www.arduino.cc/en/Guide/troubleshooting#upload
All three of these boards a brand new, all of them worked initially however all failed within several days.
Is it possible these issues are to do with how my project is wired? or is it likely to be the Nano's themself?
Any help would be greatly appreciated
