My Intel Real Sense 3D Camera in RTF is not detected

[unravelwool]

I have installed the Ubuntu system following the guidance in the page:https://github.com/intel-aero/meta-intel-aero/wiki/90-(References)-OS-user-Installation . And I have installed "Intel RealSense SDK - legacy (for R200)", but when I type "ls /dev/video*" to check if the camera drivers are correctly installed , I only found the first ten videos:video0-video10, there is no video11-13.

intel-aero@intel-aero:~$ ls /dev/video*
/dev/video0 /dev/video10 /dev/video3 /dev/video5 /dev/video7 /dev/video9
/dev/video1 /dev/video2 /dev/video4 /dev/video6 /dev/video8

And my camera is not detected.
