Device Manager displays the following message in the Device Properties dialog box, on the General tab, in the Device Status text box:
This device cannot find enough free resources that it can use. If you want to use this device, you will need to disable one of the other devices on this system. (Code 12)
Two devices have been assigned the same input/output (I/O) ports, the same interrupt, or the same Direct Memory Access channel. The assignment was made by either the basic input/output system (BIOS), the operating system, or a combination of the two.
This error message can also appear if the BIOS did not allocate enough resources to the device. You can use Device Manager to determine where the conflict is and disable the conflicting device.
