In most cases, you simply need to run "sudo adduser $USER dialout". Read on for more details.
Some helpful commands:
~ $ sudo lsusb | grep UART Bus 001 Device 002: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light $ dmesg | grep -ie cp210* [17479.466698] usb 1-1: Product: CP2102 USB to UART Bridge Controller [17479.548508] usbcore: registered new interface driver cp210x [17479.548520] usbserial: USB Serial support registered for cp210x [17479.548535] cp210x 1-1:1.0: cp210x converter detected [17480.428168] usb 1-1: cp210x converter now attached to ttyUSB0
Look at the last line, to see that the adapter is assigned to ttyUSB0. Check which groups have access to it:
$ ls -l /dev/ttyUSB0 crw-rw---- 1 root dialout 188, 0 Nov 11 13:15 /dev/ttyUSB0
In this case you should assure that your user is in the user group dialout, e.g.:
$ groups # Display the user groups for the current user user_foo : user_foo adm tty dialout fax cdrom floppy tape sudo audio dip video plugdev netdev fuse lpadmin scanner
Is the group is not listed, add your user to the group, e.g:
sudo adduser $USER dialout
You will have to logout and relogin after this command!
