Aha, that's a good point! It was silly of me to assume that if any cheap dongle works, that should mean ‘proper’ interfaces would work at least as well.

However, it seems like that explains why we needed Windows drivers, but not why device-specific Linux drivers are a thing? Unless the implication is that manufacturers who needed to make custom drivers anyway didn't bother to make their devices class compliant?
