That's a pity. I looked on the VueScan site and discovered that it does support the P-150. I wonder if the 152i is an upgrade from the 150. If so the driver might run it, perhaps minus some advanced feature(s).
I looked at the supported list for sane and found that it also appears to support the 150. Maybe you could test with that. If you have the ability you could tweak the sane driver to recognize the 152i. I did that sort of thing for a USB relay. It's just a matter of adding to a table.
The developer seems dedicated to supporting every scanner he can. Maybe you could open a conversation about whether the 150 driver would run the 152i, and whether he would make a driver for the 152i. Here's a link to the 150 driver page.

Of course this could turn into a massive PITA. With scanners so cheap maybe you could spring for a supported scanner.
Best wishes for success in your quest. I hope you find a solution.
