Update here:
I also tried:
- the Roast Time GUI “Install USB drivers”
- and the thread I mentioned in my last post. Ubuntu Linux - #4 by mcaillio
Still no luck 
Sorry should have added to my original message -R2. Where can I locate the correct product ID I should be entering?
here is my output of lsusb:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 008 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
So I’m assuming it’s vendorId:ProductId ? so 0483:a4cd
After that assumption I tried this in my /etc/udev/rules.d/99-aillio.rules file:
SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="a4cd", MODE="0666", GROUP="dialout"
but it looks like I’m missing another line based on some posts here in the thread
