This Device Manager error message indicates that the device's drivers are not installed.

Error Code

28

Display Message

"The drivers for this device are not installed. (Code 28)"

Please visit the website of the company that manufactures the device and look for the most recent drivers for this device.

For driver developers

The DEVPKEY_Device_ProblemStatus property on the device should indicate the failure code.

0xC0000490 - STATUS_PNP_NO_COMPAT_DRIVERS

PnP could not find a compatible driver for the device. This failure is often referred to as a DNF (driver not found) problem.

Examine the hardware IDs and compatible IDs of the device in question and compare to the hardware ID(s) that the INF specifies under the Models sections. Also make sure that the TargetOSVersion part of the Models section name applies to the architecture and OS version you are running on.

0xC0000491 - STATUS_PNP_DRIVER_PACKAGE_NOT_FOUND

This code indicates a missing driver package dependency.

Specifically, the INF that matched on the device uses Include entries in the INF DDInstall section to specify a Microsoft-supplied INF that is not present in this version of Windows.

0xC0000492 - STATUS_PNP_DRIVER_CONFIGURATION_NOT_FOUND

This code also indicates a missing driver package dependency.

In this case, the INF that matched on the device uses Needs entries in the INF DDInstall section to specify a section that does not exist in any Microsoft-supplied INF referenced by an Include directive.

0xC0000494 - STATUS_PNP_FUNCTION_DRIVER_REQUIRED

This failure occurs when the INF does not specify an associated function driver service.

Verify that either:

  1. The INF file for the device being installed contains an AddService directive that sets an associated service or function driver using the flag SPSVCINST_ASSOCSERVICE (0x00000002).
  2. The INF file specifies Include or Needs entries in a INF DDInstall Section that reference a system-supplied driver that in turn sets an associated service on the device.

Upgrade to Windows 10

Before upgrade, the device has a driver and is working fine. After upgrade, it shows Code 28. This is frequently caused by the driver package being excluded from the migration.
