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.

Did you use sudo when starting minicom or do you root permissions? Also what steps did you follow to setup minicom (did you use $minicom -s) before starting minicom – Santosh A
yes. I did. "sudo minicom -s" then "serial port" , tty8 -> ttyUSB0 then exit from minicom – user3665714
can you find the ttyUSB0 listed under /dev on your PC – Santosh A

It might due to not having access privilege.

Try this.

sudo chown /dev/ttyUSB0
