serial usb communication in linux using minicom

Question

I trying to use serial port in Linux. I am using minicom. When I connected my serial to USB device to a port, minicom responds with

"cannot open /dev/ttyUSB0: No such file or directory".

But when dmesg it is showing that

"converter now attached to ttyUSB0"

Then why it is not opening in minicom.

Answer 1

It might due to not having access privilege.

Try this.

sudo chown /dev/ttyUSB0
