I’m just telling you that it’s wrong to assume hardware support problem will be solved by unifying behind a single distro, while in reality device driver devs are already unified behind the linux kernel project (not distro projects) and there is not enough manpower because there are only a handful of devs have necessary skill and willing to donate their time to support random devices in the market (and they need to have the devices on their hands first for reverse engineering). As linux marketshare grows, device manufacturers may be willingly support linux on their own, so your future scanner might eventually work out of the box on linux.
