The thing is, almost all hardware accessed through drivers has tons of bugs, at least it's nowhere near as close to "bug-free" as are things like CPUs or DRAMs which cannot hide their bugs behind drivers. The thing that one can hope to work reasonably is a piece of hardware plus an accompanying driver which knows to hide that hardware's issues.
So another way of putting what you said would be "on Linux there's no working driver for that piece of hardware, unlike on Windows where the 'proprietor' went to the trouble of supplying such a driver."
