There was also the prolific serial to USB components. The market was flooded with perfectly functional clones. Prolific deliberately broke support for clones, penalizing a ton of people who had no idea.
When people did too good a job cloning some of their chips, they made the driver break even their own chips.
Of course, in this case the vendor got their stuff into the standard Windows driver without even needing users to download anything....
The ultimate effect is that our datacenter just uses Linux laptops because in practice serial adapters for Windows are just too unreliable unless we try to be supply chain detectives for the cheap little serial adapters we buy.
