F200 Intel RealSense Camera Recently not Recognized by Computer

[CVach]

I am having trouble connecting my Intel RealSense F200 USB depth sensing camera to my laptop (Lenovo G50-70 from 2014). It has connected and worked in the past and the last time I remember it working properly was about 7 months ago.

If I plug in the camera into my only usb 3.0 port, the green light on the camera doesn't blink and it is not visible in my device manager (the virtual driver was present before I uninstalled the DCM, with or without connecting the camera). However, if I plug in the camera into my usb 2.0 port, the small green light on the camera blinks, but still the camera is not visible in my device manager.

I was not sure what to do, so I has uninstalled the RealSense Depth Camera Manager, and then tried to re install it. But, when I tried to re install it it told me that it could not recognize the camera (The installer failed to detect an Intel® RealSense™ 3D camera on this system. The installation was terminated.) . Also, the Camera Explorer showed no cameras were connected.

Currently the virtual driver is not present in my Device Manager, since I uninstalled the DCM and this camera is not visible in my Device Manager.

It has worked earlier this year, and I don't think the hardware is broken. Also, my usb 3.0 port works (works with a flash drive). I have also updated the drivers in my Device Manager and unchecked the box regarding power management.

Should I downgrade to a previous version of Windows 10 I had earlier this year? Please advise me on what to do and how to connect my Intel RealSense F200 camera to my laptop.

Thank you.

Cases of 'it worked fine before until today' are often related to something that has updated in Windows and broken the camera functionality, perhaps by altering the configuration of the USB ports. So downgrading your Windows version to one in which the camera previously worked would be a good first thing to try..

I recently had this issue and resolved it. I first downloaded the latest F200 RealSense camera drivers, but was presented with a message indicating that the installer did not recognize a RealSense camera attached, even though it was connected and showed up in my Windows 10 device manager under both Cameras and Imaging devices. I tried several things, including uninstalling the drivers via Device Manager, unplugging the camera, re-plugging the camera, rebooting, etc.

But what did work in the end was opening Windows 10 Devices and Printers control panel ... Select Settings (Windows Settings gear from windows logo), select Devices. Then on right-hand side, under Related Settings, select "Devices and printers".

In the control panel window that opens, you should see your "Intel(R) RealSense(TM) 3D Camera (Front F200) displayed under a camera icon under the "Devices (xx)" section. Right click it and select "Remove Device". This will remove and uninstall all device drivers associated with the camera. (I think this is the key ... simply removing drivers from the Device Manager doesn't get all of the removed ... there's one hiding under Universal Serial Bus devices for example.

Then unplug the camera from your USB 3 port. Wait a few seconds, then plug it back in.

When Windows detects your camera after plugging it back in, it'll re-install the drivers properly. In Device Manager, open Imaging devices. You should see "Intel(R) RealSense(TM) 3D Camera Virtual Driver" listed. This is what went missing when my F200 stopped working ... and broke Windows Hello.

Now the camera should be working again, and if you install the latest Intel drivers for it, the installer should recognize the camera as present. In my case, it indicated that the latest drivers were already installed ... by giving me Modify or Remove options, but not an Install option. So I didn't have to do anything but cancel the driver install.

Hope this helps anyone who's F200 camera mysteriously stopped working. I think mine stopped after a recent Windows 10 update.
