When you try to upgrade the audio driver in Device Manager after you upgrade Microsoft Windows XP to Microsoft Windows Vista, you receive the following error message:

This device cannot find enough free resources that it can use. (Code 12)
If you want to use this device, you will need to disable one of the other devices on this system.
The device instance does not exist in the hardware tree.
This problem occurs because the Windows XP version of the Crystal SoundFusion CS4281 WDM audio driver corrupts the physical device object (PDO) of the device. This corruption changes the device number from its correct value.

Note The PDO represents the individual device on a bus to a bus driver.
