Need putty to work on /dev/ttyUSB0

I know for a fact that the port (console on a switch) is 9600 8/n/1, so it should be simple.

ttyUSB0 shows up in dmesg.

So shouldn't I be able to select /dev/ttyUSB0 in putty's serial configuration and it should work.

Works fine when I'm running putty with windows. Doesn't work with Ubuntu/putty. I get no response.

This is how I started it:

putty -serial -sercfg 9600,8,n,1,N

Any suggestions?

I use minicom. To install minicom use command

sudo apt-get install minicom

Start minicom setup with command

xxx@yyy ~ $ sudo minicom -s

You will get setup menu

enter image description here

go to Serial port setup

enter image description here

Change Serial Device

Change Bps/Par/Bits

After changes hit Enter

Save setings

enter image description here

Go to Exit to exit from setup in minicom

You minicom is ready

This is because you have not provided the read and the write permission to group of /dev/ttyUSB0 file ls -l /dev/USB0

Provide the permission: sudo chmod a+rw /dev/ttyUSB0

Putty will work fine.
