Maybe in 2002, but it's a USB webcam in 2022, if you're writing your own drivers from scratch on any platform rather than using the standards-compliant ones, I'd first wonder if you haven't got a case of NIH syndrome rather than an actual case of being constrained by the standards.

But maybe they genuinely cannot use standard protocols for some reason, then sure, writing a Linux driver might not be worth it.

I'm half assuming they do something special, half responding to the comment which describes them as a hardware company. But yes, ideally a webcam should have the basic functionality available just by plugging it in, no special software needed.
