Device Manager Problem Codes

The Device Manager marks a device with a yellow exclamation mark (!) when the device has a problem. The problem codes are in the form CM_PROB_XXX and are defined in the header file cfg.h. The most important are explained here, together with their mapping to the Device Node Status Flags. For a more comprehensive list, please see Device Manager Error Messages.

Code 1 (CM_PROB_NOT_CONFIGURED)
Indicates that the device is not installed and was not installed previously. (Corresponds to DNF_NOT_CONFIGURED.)

Code 10 (CM_PROB_FAILED_START)
Indicates that the device did not start for some reason, but the I/O Manager attempted to start it with a set of resources. (Corresponds to DNF_START_FAILED.)

Code 12 (CM_PROB_NORMAL_CONFLICT)
Indicates that there were not sufficient resources to start this device. (Corresponds to DNF_INSUFFICIENT_RESOURCES.)

Code 14 (CM_PROB_NEED_RESTART)
Indicates that user mode reconfigured the device and a reboot is required for the changes to take effect. (Corresponds to DNF_NEED_RESTART.)

Code 18 (CM_PROB_REINSTALL)
Indicates that the device needs to be installed and was installed previously. (Corresponds to DNF_REINSTALL.)

Code 21 (CM_PROB_WILL_BE_REMOVED)
Indicates that the user mode uninstalled this device. (Corresponds to DNF_WILL_BE_REMOVED.)

Code 22 (CM_PROB_DISABLED)
Indicates that the device is disabled. (Corresponds to DNF_DISABLED.)

Code 28 (CM_PROB_FAILED_INSTALL)
Indicates that the installation failed and there is no driver selected for this device, although the kernel did not report a problem (and there is no DNF_XXX match for this the problem). This problem can be the result of an on-board system device (ISA timer, ISA RTC, RAM Memory, and so forth) that does not yet have an INF file.

Code 31 (CM_PROB_FAILED_ADD)
Indicates that the device was not added. Reasons for the failure may include: a driver's AddDevice routine returned an error or there is no service listed for the device in the registry. (Corresponds to DNF_ADD_FAILED.)
