hey guys.

i hope can me.

thats error when dont use root:

code: [select]
avrdude: ser_open(): can't open device "/dev/ttyacm0": permission denied

thats error if use root:
code: [select]

avrdude: ser_open(): can't set attributes device "/dev/ttyacm0": inappropriate ioctl device
ioctl("tiocmget"): bad file descriptor

i added myself dialout group doesnt work. additionally line dont looks normal.

code: [select]
lrwxrwxrwx 1 root root 5 aug 12 13:43 /dev/ttyacm0 -> loop0

in other topics looked 1 root , dialout.
