T265 does not appear in the realsense-viewer in Qualcomm RB5 : No devices was found

[buicongnguyen80]

I found that the issue is quite similar to my issue: https://github.com/IntelRealSense/librealsense/issues/11890

Then I do as the guide here: https://developer.qualcomm.com/forum/qdn-forums/hardware/qualcomm-robotics-rb5-development-kit/68234#comment-22103 and also with this link: https://www.macnica.co.jp/en/business/semiconductor/articles/qualcomm/135331/

I do as this guide but when I connect T265 to Qualcomm RB5 device and run realsense-viewer. I receive message: There are 0 connected RealSense devices. What should I do to have T265 displayed on realsense-viewer ?

When I use dmsg and lsusb and usb-devices to check the connected device, It look like this problem : https://github.com/IntelRealSense/librealsense/issues/4681

However, in RB5, I plug and unplug the T265 but there is no change. No device was detected. Thank you and still wait for the support.

Ensure that you are using the correct version of realsense-viewer. T265 was discontinued and removed from the reading software.

Yes, I use according to the guide from Qualcomm : https://developer.qualcomm.com/forum/qdn-forums/hardware/qualcomm-robotics-rb5-development-kit/68234#comment-22103 In this link, they clone with the branch 2.53 which still support T265. The remain issue is: T265 still recognized as another device: 16532.032728] usb 1-2.3: new high-speed USB device number 88 using tegra-xusb [16532.054736] usb 1-2.3: New USB device found, idVendor=03e7, idProduct=2150 [16532.054753] usb 1-2.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [16532.054765] usb 1-2.3: Product: Movidius MA2X5X [16532.054777] usb 1-2.3: Manufacturer: Movidius Ltd.

You should try version (v2.50.0) or (v2.51.1). If the problem persists, you should try updating the firmware using realsense-viewer.

https://github.com/IntelRealSense/librealsense/releases/tag/v2.51.1

Yes, I have just reset RB5 board, install again from beginning. Then I do: https://github.com/IntelRealSense/librealsense/blob/R/251/doc/libuvc_installation.md download source file librealsense-2.51.1 to the RB5 device unzip,

Make sure no RealSense device is connected Open the terminal, run:

$ chmod +x ./libuvc_installation.sh $ ./libuvc_installation.sh Wait until Librealsense script completed message is displayed (may take some time) Connect RealSense device Run rs-enumerate-devices from the terminal to verify the installation

But the problem is still there. I use usb-devices then I have seen the camera is recognized as Movidius Ltd. device.

I opened realsense-viewer but no device was showed up. I test with PC Windows 11, there is no problem with the camera and cable. May you suggest the way to fix it ? I have seen similar issues with NVIDIA Jetson but it was fixed long time ago. May you add the fix to RB5 Qualcomm too ?

I use USB MicroB with one USB 3.0. I checked with the cable which has 2 USB port, 1 USB 2.0 for supplying more power and 1 USB 3.0. The problem still exist.
