The documentation necessary to build a device driver may be mixed with other things, not relevant to how the device works. For example, you might have electronics schematics, competition comparisons, or even future plans for the device. And the company might not want to devote the time needed to separate it. An NDA might specify that the developer may not divulge any information not relevant to the device driver.
