That should be a symlink to the actual tty device.  On my system it is 
/dev/ttyUSB0.


pi@pi2:~ $ ls -l /dev/serial/by-id
total 0
...
lrwxrwxrwx 1 root root 13 May 17 10:50 
usb-Silicon_Labs_CP2102_USB_to_UART_Bridge_Controller_IC-7300_02034059-if00-port0 
-> ../../ttyUSB0

So in logcfg.dat:

RIGMODEL=373
RIGPORT=/dev/ttyUSB0
RIGSPEED=19200

I recall the USB driver for that chip is picky about the baud rate, and 
I think I had to set it to 19200 to make things work.

The ttyUSBx device name can change on reboot if you have multiple USB 
serial devices.  Hence the previous suggestion to create a unique name 
via a udev rule.

On my system I created:
/etc/udev/rules.d/99-radio.rules

which contains the lines:

SUBSYSTEM=="tty", KERNEL=="ttyUSB*", ATTRS{idVendor}=="10c4", \
ATTRS{idProduct}=="ea60", SYMLINK+="ttyUSB-ic7300"

Udev will then always create a unique symlink: /dev/ttyUSB-ic7300 that 
you can use as the RIGPORT.
