Realsense camera works randomly

[Quentin_S_]

Hi everyone,

I've received my Realsense camera 1 week ago. I tried install the SDK with the offline package  intel_rs_sdk_offline_package_r_2.0.30.73832 but the camera isn't recognized at all.

I decided to buy a new computer with a 4th generation Intel processor. First installation after a fresh Win 8.1, the camera and the samples works. Unplug/plug the camera, the device and samples binaries doesn't work anymore. Even after a reboot of the machine (many tries with camera plugged, ad unplugged). I reset my computer, and install again Win 8.1. The camera works randomly : (around 7 install of win 8.1 for making the camera works 3 times at the very first SDK installation)

Following the tutorial of Marty G. I installed Win 10 preview to make a try. It works once, same problem than with Win 8.1 OS. Reboot and re-plug  make windows not recognize the device.

I tried both Windows version with the new SDK installer version :   3.1.0.85181, exaclty the same problem.

I looked up the drivers used (in device manager) for the 3D camera RGB, and 3D camera Depth (Imaging Devices categorie). For both, drivers are : CtClsFlt.sys, ksthunk.sys, usbvideo.sys. And the 3D Camera Virtual Driver uses : CtClsFlt.sys, ksthunk.sys and RealSenseDCM.sys.  Sometimes, after a SDK re-installation on Win 10, when the RGB and Depth Camera appears in the device manager, driver listed is only : usbvideo.sys. In this case too, Firmware cannot be installed, and samples binaries failed during init step.

On Win 8.1, after a new installation, RGB and Depth Camera, arn't visible, but they can be shown using "show Hidden devices" in the menu of device manager. Looking at the drivers, they are all here (3 drivers for the 3 device in Imaging Devices) but windows doesn't want to recognizes the devices. In properties, error message is : << The device isn't connected to the computer, error code 45 >>. Solution suggested by Windows : plug/unplug -> That doens't works.

I cannot start working on my ideas, because, event if the camera start working on a fresh Windows installation, first reboot or unplug makes it stop.

I tried re-install msi packages one by one which can be found in your AppData/Local/Temp/{11122233344...}/ folder used during the decompression of sdk executable. It may the camera works once after the installation of  intel_rs_sdk_runtime_intel64_lbdriver_win8_24922.msi and intel_rs_sdk_runtime_intel64_ivcam_24922.msi.

Looking at the log of the installation of the SDK, when installing the 3D camera virtual driver, the installation "didn't not occurs" because of "the current driver on the device is the same or better" anyway the last message of this log is "Intel Realsense 3D camera virtual driver -- Installation completed succefully". The same log messages can be found for the installation of intel_rs_sdk_runtime_intel64_xcservice_24922.msi (Depth camera manager service).

Main computer : Intel Core i7-3820 CPU   -   MSI  x79a-gd45 - 16Go Ram - USB3 - Win 8.1 64bits

New computer : Intel core i5-4460 CPU - MSI  H97 PC MATE -  8Go ram -  NO GPU : mother Board chipset used - USB3 - Win 8.1 / Win 10 64bits

PS : sorry if the messages arn't exaclty the same, i put translations, my windows on my main computer isn't in english.

Any ideas, any suggestions, new tests to do, are welcome. I don't know what to try next...

Hi all,

I have the same problem and it seems to be a known problem in Windows8 (W8.1 pro too) + USB3 + Intel (R) USB 3.0 Extensible Host Controller -0100 (Microsoft).

Some people says they solve the problem installing a hacked driver from Windows7, but I don't think it's a good solution.

For now, I can work with the RS making a system full shutdown  (cmd.exe > shutdown /s /t 0 ) every time that the RS goes crazy.

For those who want to try the hacked driver solution search "windows8 and intel usb3 host controllers pluggable" at google, first result ( sorry about that but the spam filter blocks me if I write the link)

Happy coding!
