I'm guessing it's Primax. I did some data captures from WinXP in a VM, exercising every button along with some test scans including an IT87 calibration target. Also a OneTouch 9320 scanner with a 35mm slide/negative scan function (only tested the 35mm backlight since I'm missing the film templates and it won't scan without them). Data dumps and scan PNGs here:

Models from the rest of the product line are available on eBay. P.S. If you're wondering why it took 5 years it's because I plugged my laptop power supply into the scanner by accident and fried it. It wasn't until someone gave me another that I remembered to report back on it.
