如何在ubuntu中将inter realsense viewer v2.53.1降级到inter realsense viewer v2.50.0

可以按照以下步骤将 Intel RealSense Viewer 从 v2.53.1 降级到 v2.50.0：

1. 卸载 v2.53.1 版本：

   sudo apt-get remove intel-realsense-dfu*
   sudo apt-get remove intel-realsense*

2. 下载 v2.50.0 版本的软件包：

   wget https://github.com/IntelRealSense/librealsense/releases/download/v2.50.0/librealsense2-dkms_2.50.0-0ubuntu1~18.04.1_amd64.deb
   wget https://github.com/IntelRealSense/librealsense/releases/download/v2.50.0/librealsense2-utils_2.50.0-0ubuntu1~18.04.1_amd64.deb
   wget https://github.com/IntelRealSense/librealsense/releases/download/v2.50.0/librealsense2-dev_2.50.0-0ubuntu1~18.04.1_amd64.deb

3. 安装 v2.50.0 版本的软件包：

   sudo dpkg -i librealsense2-dkms_2.50.0-0ubuntu1~18.04.1_amd64.deb
   sudo dpkg -i librealsense2-utils_2.50.0-0ubuntu1~18.04.1_amd64.deb
   sudo dpkg -i librealsense2-dev_2.50.0-0ubuntu1~18.04.1_amd64.deb

4. 安装完成后，连接 RealSense 设备并运行以下命令来检查设备是否被正确识别：
