because you are not user root, nor are you in group dialout,
presumably. 
so you do not have any access to that port.


run putty as root (not good longterm, but a quick check)

$ sudo putty -serial /dev/ttyACM0

add yourself to the dialout group, then logout and back in.

$ sudo usermod -a -G dialout $(whoami)

check you are in the dialout group with the id command

$ id
uid=1000(alice) gid=1000(alice) groups=1000(alice),10(wheel),18(dialout)


then you will always have access to that port, and other serial ports
