Hauppauge PVR 1212

This sounds a bit strange, but here goes....
I have a really old Hauppauge PVR 1212 capture device. It works fine in Windows with my video camera (HDMI -> component) on OBS v29 with the Hauppauge driver.
However, it does not work under OBS V29 for Linux (I'm using Mageia 9) There is a Linux driver for it (hdpvr) for it. It has been a kernel module for years. OBS V29 for Linux shows it as being there....I can select it as a source. But it has no input or output...just a black screen.
Does anyone have any idea why?
Thank you.
