do you see any /dev/tty devices when doing the directory listing like I suggested in my prior post? if you don't see any you may have an issue with the USB not working properly. if that is the case no program will work if it's not detecting your serial device.There is no /ttyACM0 showing. When setting USB0 or ACM0 I get error message "not found". With dmesg the new device is showing . Is there no other program or tip ?
with SuperZaxxon by default should have authority to the tty devices as all user belong to the wheel group which should allow anyone to access the tty devices.What are the rights on the device ?
