My old laptop is starting to stumble after a decade of solid service, so I bought a new one and darned if I can get it properly configured.

Laptop - Acer Nitro 5 running Ubuntu 20.04
Rig - IC-7300

WSJT-X v2.1.2

Gee, that's old! Please upgrade to 2.5.4!

Settings (btw, same as old laptop which controls my rig just fine)
Serial Port: /dev/ttyUSB0
Baud Rate 115200
Data Bits: 8
Stop Bits: 1
Handshake: None
PTT Method: CAT
Mode:USB
Split operation:Rig
Audio: alsa_<input and output>.usb-Burr-Brown_from_TI_USB_Audio_Codec-00.analog-stereo (both set to mono)

Hamlib error when attempting to Test CAT: Protocol error while getting current frequency

I've verified I'm in the dialout group.

Any ideas?

Are you sure that your rig is actually /dev/ttyUSB0 ?

With rig connected pen terminal and do:

ls -l /dev/serial/by-id/

This will show you the actual tty device IC7300 is linked to. Something like this:

lrwxrwxrwx 1 root root 13 loka  10 08:32 usb-Silicon_Labs_CP2102_USB_to_UART_Bridge_Controller_IC-7300_03003103-if00-port0 -> ../../*ttyUSB0*
