trying to connect a PWM pro charge controller to Venus OS

Im trying to connect a PWM pro charge controller to Venus OS, but Venus OS does not see it.
I have a RPI running Venus OS large. It happily runs an MPPT , inverter and 2x BMS.
Im now trying to connect a PWM pro charge controller which runs a second solar and 12v Pb in the same remote location. I have the victron cable RS485 to USB. but it does not show in the device list.
Using SSH to the RPI i can run
$ lsusb i can see the device as: Bus 001 Device 011: ID 04e2:1411 Exar Corp.
The Victron Manual from 2015 talks about installing the drivers using their free Windows program. My problem with this is i dont have any Windows machines only lynux/ubuntu/rpi.
All other documentation relating to the PWM pro just says that it is programmable via Venus OS with no mention of drivers or other.
I have victronconnect and VRM all setup with Venus OS Large on a Raspberry pi.

Any ideas would be gratefully received.

with no other advice from Victron other than

"PWM pro is programmable via Venus OS" with no further details

im now looking at using node-red to interface with the PWM.

I really wouldn't have brought this PWM if i had known it wasn't do-able with venusOS


any suggestions very welcome
