ColorHugALS doesn't work on Windows 10

[iXPe...@yahoo.com]

ColorHugALS doesn't work on Windows 10. From some research i think the HID implementation should be updated to be compatible with Windows 10. Is it possible to do that?

It should already support SensorHID with the latest firmware. What
firmware do you have installed?

The firmware version is 4.0.3 . 

In device manager i have 2 devices: 

1. unknown device "4.0.3" ;

  2. HID Sensor Collection V2.

Tried Sensor Diagnostic Tool:

 - on Windows 8 it detects the device and can read sensor values. 

 - on Windows 10 the ambient light sensor is missing.

Hmm, I've only ever tested on Windows 7 and 8, but indeed you're right
as my updated VM shows the same thing.

Do you know any more details why? If you could do some research I'm
happy to add any more required parts of the SensorHID implementation
but I can't really spend hours working this out myself for a
very-much-EOL product. Sorry that's not more helpful.

Ok, I will try to investigate further. Do you have specific documentation on Sensor HID when you wrote the implementation?

Now i'm reading

https://msdn.microsoft.com/en-us/library/windows/hardware/dn613934(v=vs.85).aspx

But i'm not sure if i am on the right path.

Hi,

I've cc'd the person who wrote the original code. Benjamin: Do you
know why the ColorHugALS device works in Window8 but doesn't work in
Windows 10? I think you're very much the expert here.

Thanks,

Richard.

I had no idea it was working on Win8 :)
I suspect the driver changed in Win10, but I have no way to tell you
precisely what changed. There might be some explanation on msdn, but a
quick google lookup doesn't show an immediate result.

Sorry,
Benjamin
