Запуск глубокой камеры Intel Realsense R200 на Ubuntu 18.04 LTS

Я пытаюсь запустить глубинную камеру Intel Realsense R200 на Ubuntu 18.04 LTS.

Мое ядро ​​4.18.0-20-generic Я следовал инструкциям по этой ссылке

но все равно я получаю следующие сообщения при подключении камеры:

    mkhuthir@MuthDT:~$ sudo dmesg

Когда я пробую любой из включенных примеров, я получаю следующее:

mkhuthir@MuthDT:/usr/local/bin$ ./rs-hello-realsense 
RealSense error calling rs2_pipeline_start(pipe:0x55d01fb185f0):
    No device connected
mkhuthir@MuthDT:/usr/local/bin$

проблема, кажется, с uvcvideo. Кто-нибудь может дать мне подсказку, как это исправить?
