Drivers of devices already connected with the PC are saved in a backup file by the Windows operating system. Possibly, this file, which includes all of those "known" devices, is corrupted. This could have happened by a previous installation of a driver related to another device which failed or due to information saved in an incorrect way to the file. Thus, in such a case this file should be deleted manually.

This problem affects all Windows operating systems starting from Windows 2000!
