D457 USB compatibility in production
Hello,
I'd like to know if besides GMSL/FAKRA the D457 camera supports USB the same way it does in D455. The tech specs mention - "It also supports USB 2.0/USB 3.1 for debug purposes and production line only." What is meant by "production line"?

Hi Martin Kambla A range of reference sources for the new D457 camera is available at the link below.
https://github.com/IntelRealSense/librealsense/issues/10984
On pages 14 and 20 of the dedicated data sheet document for the D457, further information about USB compatibility is provided in the extracts shown below.
In regard to the line that you quoted that is also included in the above extracts, the Firmware section on page 40 of the data sheet states: "D457 firmware can be updated through USB in USB debug mode, or through I2C in MIPI/GMSL mode".
Whilst a USB port is provided for firmware updates and debugging purposes, the D457 is designed for use with GMSL/FAKRA.

There is further information about USB and GMSL/FAKRA at the official D457 FAQ.

The notes for the pre-release version of RealSense SDK 2.52.1 states "Validation of USB legacy devices with a unified USB+MIPI LibRS (LibRealSense) is ongoing", adding that no major issues are expected.

Update: the D457 is now listed as in stock at the RealSense Store.

I bought 10 pieces of D457 for robotic project. I prefer D457 for IP certification instead of D455. Unfortunately I was not suspecting limitation on usb port. On my tests my findings are it detect the camera as d455 and lots of time it connects with 2.1 usb . But sometimes it connect with 3.2 usb support and I could get all datas with high resolution and high fps without any limitation . It seem the usb port limitation is not related from hardware. It has capability to transfer all data. Fakra is not common I/O for standard PC's. I will use this cameras with Intel NUC pcs. Is there a way to use this cameras with NUC pcs.

Hi Baris Bilgin,
Thanks for reaching out to us.
Please use the following method to solve the connection issue:- Use the latest firmware and RealSense SDK 2.0 version.
- Connect the camera directly to a USB 3 port on your PC. If the camera is already connected directly to the PC, try using a powered USB hub.
- Use the USB cable that came with the RealSense camera. The cable that came with your RealSense Camera is a high-quality USB cable that is capable of handling the power and bandwidth requirements of the camera. Using other cables is not recommended.
- Connect the RealSense camera to a different computer - preferably a computer with an Intel processor. If your camera works on another computer, then the original computer probably has a USB subsystem that the camera is having problems with.
- Flip the USB C connector that is inserted into the camera and re-insert it the opposite way. Sometimes the camera will work only if the cable is inserted in a particular orientation.
- Update the USB drivers on the PC. You probably already have the latest USB drivers due to automatic Windows Updates but this is worth checking.
For your information, integration of the Intel® RealSense™ into a platform requires a GMSL/FAKRA de-serializer connecting to the Host platform. To order Intel® RealSense™ Vision Processor D4 GMSL/FAKRA De-serializer Board, please refer to Intel® RealSense™ Vision Processor D4 GMSL/FAKRA De-serializer Board.

If you require dust and water protection and would prefer to use the D455 camera model, the company autoVimation offer a protective enclosure for the D455 model that has IP66 and IP67 protection (better water protection than IP65).

Thank you Waix Fook Wan,
Flip the USB C connector that is inserted into the camera and re-insert it the opposite way. Sometimes the camera will work only if the cable is inserted in a particular orientation. That solve my issue. Rest of them already done before. Now I can run camera without any issue.
Dear Javier,
Everything looks ok for now. In Realsense-Viewer and ROS2 driver I could get data without any limitation. I will give further information multiple camera performance in long usage.
Dear MartyG,
Thank you for your recommendation. In my case dust protection is much important to protect camera life and decrease maintenance time. I gonna use in industrial application. I evaluate this products for next projects.

Hi Martin Kambla and Javier and Baris Bilgin I have received information from Intel that it is fine to use the D457 only in USB mode and it has the same USB performance and the same feature-set as the D455, with the added IP65 protection. So it is absolutely valid to purchase the D457 for the protection and use it as a USB camera instead of in GMSL / FAKRA mode.
They also re-affirmed the advice to flip the D457's USB-C connection to the opposite orientation if the camera is not working.
