udev (userspace /dev) is a device manager for the Linux kernel. It can be used for the following:

  • Add actions to the attachment/removal of certain devices.

  • Make devices available without root privileges.

  • Recognize older devices

  • Load UVC extension units.

The udev rules file is generated during the build step; the template is located at data/udev/

The default installation path is: /etc/udev/rules.d

For more information, refer to the man pages of udev (7,8).
