7.3.3.6. Udev does not create a device
Further text assumes that the driver is built statically into the kernel or already loaded as a module, and that you have already checked that Udev doesn't create a misnamed device.
Udev has no information needed to create a device node if a kernel driver does not export its data to sysfs. This is most common with third party drivers from outside the kernel tree. Create a static device node in /lib/udev/ devices with the appropriate major/minor numbers (see the file devices.txt inside the kernel documentation or the documentation provided by the third party driver vendor). The static device node will be copied to /dev by udev.
