“Cannot install this hardware. Error occured during installation of the device. Driver installation file for this device is missing a necessary entry. May be because the INF was written for Win 95 or Later. Contact your hardware vendor.”

This error message refers to a problem with your computer’s configuration and should be investigated with your computer’s manufacturer if none of the other tips help. In your Windows INF directory (usually C:\Windows\INF) there should be three files installed with Windows called usb.inf, wdmaudio.inf and wdma_usb.inf. If any of these is missing you may encounter the error message. To restore one of the missing files, you can try reinstalling Windows, repairing Windows from the original installation CD or copying it from another computer running the same version of Windows as yours. We are unable to provide copies of working INF files; please contact your computer manufacturer for further help with this problem.
