Has anyone got the Arducam OV9281 working w Raspberry + Ubuntu?

Hi All,
I’m struggling to get this camera to work with my RPi4 + Ubuntu 18.04.
It works fine when I’m in Rasbian OS but doing the exact same things doesn’t work under Ubuntu.
I never get the /dev/i2c-0 device that I get under Raspbian. I do get a /dev/i2c-1 but it does not get the gpio pin registration.

I would love to hear if anyone can confirm that this has worked for them?

Cheers
