Hi Maik,
Thanks for your note. Yes, another software especially a software from OEM vendors may cause such problems. We rely on Windows notifications about changes in hardware configuration and if a vendors' software block this notifications we had troubles detecting changes (moreover Windows also has such troubles).
Let us know if you have any further experience with this problem. And sorry for my so delayed response.
