Is there a requirement to offer a device driver? Usually there is an API

This is _NOT_ generally true of USB devices, especially on windows.

With the exception of some very standardized things like keyboards and
mice, the hardware vendor, and not the operating system vendor, is
expected to provide the device driver.

Things are a little different in the case of linux where manufacturer
support has been lacking and drivers are getting packaged with the
operating system.
