![]() How to Manage Device Drivers with Command Line - Tech. Net Articles - United States (English)(what is this box?)Generally speaking, the best tool to manage device drivers is “Device Manager”. That is a GUI snap- in for. Microsoft Management Console (MMC). You can start it by launching. But that's not an options in some specific cases, namely: Scripting. Windows Server installed in Server Core option. In these cases you need a command- line tool. Microsoft provides two such tools that differ both in their capabilities and availability. Plug- and- Play (Pn. P) Utility (PNPUtil. Basic Features: List drivers - PNPUTIL. EXE - e Add driver. Pros: Included out of the box with all current Windows versions. Syntax complexity is medium. Cons: Does not provide advanced functionality such as. Disable device. Select one specific driver for specific device from the list of compatible drivers that are currently installed in the system. Device Console (Dev. Con. exe)Features (also Pros): All device and driver management functionality that can be found in Device Management MMC including advanced functionality such as. Disable device. Select one specific driver for specific device from the list of compatible drivers that are currently installed in the system. Syntax complexity is high.

Specifying Driver Load Order. Last Updated: 7/3. For most devices, the physical hierarchy of the devices on a computer determines the order in which Windows and the Pn. P manager load drivers. Windows and the Pn. P manager configure devices starting with the system root device, and then they configure the child devices of the root device (for example, a PCI adapter), the children of those devices, and so on. The Pn. P manager loads the drivers for each device as the device is configured, if the drivers were not previously loaded for another device. Settings in the INF file can influence driver load order. This topic describes the relevant values that vendors should specify in the service- install- section referenced by a driver's INF Add. Service directive. Specifically, this topic discusses the Start. Type, Boot. Flags, Load. Order. Group, and Dependencies entries. Drivers should follow these rules for specifying Start. Type: Pn. P driver. A Pn. P driver should have a start type of SERVICE. Such a driver should have the start type SERVICE. If a driver services both Pn. P and non- Pn. P devices, it should set this start type. Non- Pn. P driver that must be started by the service control manager. Such a driver should have the start type SERVICE. Pn. P drivers must not set this start type. A Pn. P driver should be written so that it can be loaded when Windows configures a device that the driver services. Conversely, a driver should be able to be unloaded any time that the Pn. P manager determines that there are no longer devices present that the driver services. The only driver load orderings that Pn. P drivers should depend on are as follows: The drivers for a child device can depend on the fact that the drivers for the parent device are loaded. A driver in the device stack can depend on the fact that any drivers below it are loaded. For example, the function driver can be certain that any lower- filter drivers are loaded. However, be aware that a driver in the device stack cannot depend on being loaded sequentially after a device's lower drivers, because the driver might are loaded previously when another device was configured. Filter drivers in a filter group cannot predict their load ordering. For example, if a device has three registered upper- filter drivers, those three drivers will all be loaded after the function driver but could be loaded in any order within their upper- filter group. If a driver has an explicit load- order dependency on another driver, that dependency should be implemented through a parent/child relationship. A driver for a child device can depend on the drivers for the parent device being loaded before the child drivers are loaded. To reinforce the importance of setting the correct Start. Type value, the following list describes how Windows and the Pn. P manager use the Start. Type entries in INF files: On system startup, the operating system loader loads drivers of type SERVICE. These drivers are in memory when the kernel gets control. Boot- start drivers can use INF Load. Order. Group entries to order their loading. The child devices are configured and started if their drivers are also boot- start drivers. If a device's drivers are not all boot- start drivers, the Pn. P manager creates a device node (devnode) for the device but does not start the device yet. After all the boot drivers have loaded and the boot devices are started, the Pn. P manager configures the rest of the Pn. P devices and loads their drivers. The Pn. P manager walks the device tree and loads the drivers for the devnodes that are not yet started (that is, any nonstarted devnodes from the previous step). As each device starts, the Pn. P manager enumerates the children of the device, if any. As it configures these devices, the Pn. P manager loads the drivers for the devices, regardless of the drivers' Start. Type values (except when Start. Type is SERVICE. Many of these drivers are SERVICE. The load ordering is based on the physical device hierarchy.
