Code 10 - CM_PROB_FAILED_START

  • Article

This Device Manager error message indicates that the device failed to start.

Error Code

10

Display Message

If the device's hardware key contains a "FailReasonString" value, the value string is displayed as the error message. (A driver or enumerator supplies this registry string value.) If the hardware key does not contain a "FailReasonString" value, the following generic error message is displayed:

"This device cannot start. (Code 10)"

"Try upgrading the device drivers for this device."

Select Update Driver, which starts the Hardware Update wizard.

This error code is set when one of the drivers in the device's driver stack fails IRP_MN_START_DEVICE. If there are many drivers in the stack, it can be difficult to determine the one that failed.

See the DEVPKEY_Device_ProblemStatus property on the device for the failure code returned for the start IRP.

For additional information, see Retrieving the Status and Problem Code for a Device Instance.

For driver developers

One of the drivers in the device stack failed the start IRP. The DEVPKEY_Device_ProblemStatus property on the device should indicate the failure code.

If one of the drivers in the device's driver stack is a UMDF driver and the DEVPKEY_Device_ProblemStatus property on the device is STATUS_DRIVER_PROCESS_TERMINATED, this information may be helpful for the owner of the driver to diagnose the problem:
