Program Do Sprawdzania Hardware Identification
Hardware ID. 2 minutes to read.In this articleA hardware ID is a vendor-defined identification string that Windows uses to match a device to an INF file. In most cases, a device has associated with it a list of hardware IDs. (However, there are exceptions − see Identifiers for 1394 Devices reports a list of hardware IDs for a device, the hardware IDs should be listed in order of decreasing suitability.A hardware ID has one of the following generic formats:This is the most common format for individual PnP devices reported to the Plug and Play (PnP) manager by a single enumerator.

New enumerators should use this format or the following format. For more information about enumerator-specific device IDs, see.The asterisk indicates that the device is supported by more than one enumerator, such as ISAPNP and the BIOS. For more information about this type of ID, see. Selecting a hardware IDRoot enumerated devices sharing generic namespace such as ROOTSYSTEM may cause conflicts and yellow-bang in device manager on OS upgrade.To prevent this, use a unique namespace for each driver that includes a root enumerated device. For a USB or system device, instead of using ROOTUSB or ROOTSYSTEM” use ROOTCOMPANYNAMEDEVICENAME. In addition, the driver installer code should check to see if the devnode is already present and take any necessary corrective action before installing.An existing device class that has established its own naming convention might use a custom format. For information about their hardware ID formats, see the hardware specification for such buses.
New enumerators should not use this format.The number of characters of a hardware ID, excluding a NULL terminator, must be less than MAXDEVICEIDLEN. This constraint applies to the sum of the lengths of all the fields and any ' field separators in a hardware ID. Drivers in labview for dummies. For more information about constraints on device IDs, see the Operations section of. Obtaining the list of hardware IDs for a deviceTo obtain the list of hardware IDs for a device, call with the DeviceProperty parameter set to DevicePropertyHardwareID.
The list of hardware IDs that this routine retrieves is a value. The maximum number of characters in a hardware list, including a NULL terminator after each hardware ID and a final NULL terminator, is REGSTRVALMAXHCIDLEN. The maximum possible number of IDs in a list of hardware IDs is 64. Examples of Hardware IDsIn the following, the first example is a for a PnP device, and the second example is an:root.PNP0F08PCIVEN1000&DEV0001&SUBSYS00000000&REV02 See AlsoRecommended Content.
