Have to unplug Nano every time I upload sketch (OS X 10.10.5 / IDE 1.6.5)

Using Arduino IDE 1.x

Hi,

Every time I upload a sketch to my Nano 3.2 I have to unplug the USB cable or else I get the:

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
avrdude: stk500_recv(): programmer is not responding

Is there a workaround for this?

br,
Martin

Sound like a driver problem to me...

Is the board running fine after uploading without unplugging?

Try another computer.

Which board do you have? (Which serial-USB chip?)

Try other drivers.
