RAMBO has the odd behaviour that is powers usb connection over usb but not processor. So in normal browser gui when setting up printer ensure the printer has also main power selected. Select firmware marlin or connection will not work. Select port it offers and correct baud rate and connection should work. In printer configuration you can also select that port is visible even if firmware is not running. That will prevent showing the failed connection retries when main power is off.
If that does not help, please describe exactly what you have configured and what happens so we have a chance to see where you did go wrong.
Then check a the port is correct. There are manny ports on linux but only is correct. If you in config click on ports you see all available port. The right one is that, that vanishes if you unplug printer. Since you know firmware already I assume you have set it right. Then only baud rate may be wrong. Also look at the connection sign color. If it is gray the printer is deactivated and won't try to connect. Red mean unconnected but will try to connect. Green is connected. if it is green you can call the console and enable ACK and send a test command

and should get a response in screen below. Then you know connection is really good and you can proceed.
