First, if you have installed any 3rd party drivers, potentially via alternative calibration systems such as used with Argyll, HCFR, Displaycal, etc., uninstall them.
Such drivers will not work with ColourSpace.
Second, ColourSpace very deliberately uses exclusive modes for hardware connections.
This means that if drivers are being accessed by other software, ColourSpace will not connect.
If you have hardware connection issues, check for 3rd party programs and services that may be causing such problems.
To see such programs and services use Task Manger, and look at all Running Services.
Even totally unrelated manufacture specific software/services can cause such issues... specifically any alternative calibration programs, as well as RGB Lighting programs/services.
For example, just about all software from Gigabyte has proven to cause connection problems.
LG have confirmed that their Calibration Studio can potentially cause such issues.
And X-Rite's i1Profiler can cause issues, including their X-Rite Device Manager software.
Also Dell's Alienware software has been proven to cause issue with i1D3 connections.
And even non-related software, such as Logitech Services, have been proven to cause issues.
Unfortunately, there is a lot of bad software out there, often manufacturer bloatware, as seen above...
To isolate the issue, if it is being caused by a 3rd party program or service - rather than a driver - prevent all such programs/services from running on 'Start-up', re-boot the PC, and verify ColourSpace can connect with the hardware in question.
Then enable each program/service in turn, to define which is causing the issue.
As a minimum, any 3rd party software/services that caused a problem should be prevented from running in the background, and a full uninstall may likely be required, including uninstalling any associated drivers, to enable ColourSpace to operate correctly.
