Routine Description:

/*++
Routine Description:
This routine sets the configuration-specific configuration flags for a
device instance and hardware profile combination. If the
CSCONFIGFLAG_DO_NOT_CREATE bit is set for an existing device instance
in the current hardware profile, it will be removed. If the
CSCONFIGFLAG_DO_NOT_CREATE bit is cleared in the current hardware profile,
the entire hardware tree will be reenumerated, so that the parent of the
device instance has the chance to create the device instance if necessary.
Parameters:
pDeviceID Supplies the address of a null-terminated string that
specifies the name of a device instance to modify.
ulConfig Supplies the number of the hardware profile to modify.
If 0, the API modifies the current hardware profile.
ulValue Supplies the configuration flags value. Can be a
combination of these values:
CSCONFIGFLAG_DISABLE Disable the device instance in this
hardware profile.
CSCONFIGFLAG_DO_NOT_CREATE Do not allow this device
instance to be created in this hardware profile.
ulFlags CM_SET_HW_PROF_FLAGS_UI_NOT_OK
If this flag is specified then the OS will not display the
reason that the device failed to be disabled or removed.
hMachine Machine handle returned from CM_Connect_Machine or NULL.
Return Value:
If the function succeeds, the return value is CR_SUCCESS.
If the function fails, the return value is one of the following:
CR_INVALID_FLAG,
CR_INVALID_POINTER,
CR_REGISTRY_ERROR,
CR_REMOTE_COMM_FAILURE,
CR_MACHINE_UNAVAILABLE,
