acquire_power failed: D405 camera, Win10 laptop, and USB3 ExpressCard

[hexaflexa]

I am trying to get a new D405 RealSense camera working on an old Win10 laptop with a USB3 ExpressCard (which shows up in device manager as "Renesas USB 3.0 eXtensible Host Controller")

When I launch RealSense Viewer, I get error:

sensor.cpp:661 - acquire_power failed: MFCreateDeviceSource(_device_attrs, &_source) returned: HResult 0x80070005: "Access is denied"

(The D405 camera did work on a different Win 10 PC (desktop machine), i.e. able to view images using RealSense Viewer)

Is there any workaround for the acquire_power failed error on the laptop? Is connecting through the USB 3.0 ExpressCard the problem?

Hi @hexaflexa This error can occur if a particular Windows computer's privacy permissions to access the camera are not set to On. Instructions for doing so can be found at #3381 (comment)
