I am using cutecom for sending serial commands to my FTDI Device, which is connected in /dev/ttyUSB0. But i am unable to connect through Cutecom and input text box is disable.

When i am pressing Open Device it is showing unable to open /dev/ttyUSB0.

I checked $lsusb Ftdi device is connected. Why it is so? Help me. enter link description here


This sort of thing is frequently caused by permissions on the serial devices. Is there any change if you run cutecom as root? If so, adding your user account to the 'dialout' group ought to do the trick.
