Code 51: This device is currently waiting on another device or set of devices to start
Published: June 1, 2011

Device Manager displays the following message in the Device Properties dialog box, on the General tab, in the Device Status text box:
This device is currently waiting on another device or set of devices to start. (Code 51).
The device did not start because it has a dependency on another device that has not started. This error is likely to have occurred due to the failure of a Simple Peripheral Bus (SPB) controller, such as an I2C or Serial Peripheral Interface (SPI) controller; the controller’s failure causes attached devices to fail as well.
Review the error code for the SPB controller to diagnose the reason for the controller’s failure.
