I use a ic-7300 and have it set to use USB0, but I get no rig control.
Not sure how to correct this, the 7300 uses a symlink to USB0, so how
do I get this to work ?

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

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.
