A 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 more than one hardware ID associated with it. Typically, a list of hardware IDs is sorted from most to least suitable for a device.

To find hardware ID for a given device, follow these steps:

Typically, when you create a new hardware ID for your device, you'll use one of the following generic formats:
Home and hardware go hand in hand when matching home safety with decor and design. We have plenty of hardware options designed to make your home safe and secure while also providing a finished look and style that’s all yours – from the front door to the kitchen to the bedroom and bathroom. Hardware is used for installations, repairs, or maintenance tasks in industrial and commercial facilities. Braces and brackets reinforce and support shelves, railings, panels, furniture, and other equipment and surfaces. Door closers, hinges, handles, knobs, and other door hardware allow doors to open and close so people can pass.
<enumerator><enumerator-specific-device-ID>
This is the most common format for individual PnP devices reported to the Plug and Play (PnP) manager by a single enumerator.
*<generic-device-ID>
The asterisk indicates that the device is supported by more than one enumerator, such as ISAPNP and the BIOS.
<device-class-specific-ID>

Cabinet HardwareSelecting a hardware ID
Root enumerated devices sharing generic namespace such as
ROOTSYSTEM Back in time 5 1 1. may conflict and result in an yellow-bang error icon in Device Manager when updating Windows.
You can prevent this by using a unique namespace for each driver that has a root enumerated device. For a USB or system device, instead of using
ROOTUSB or ROOTSYSTEM” use ROOT[COMPANYNAME][DEVICENAME] . Then, before installing, check to see if the devnode is already present.

The number of characters of a hardware ID, excluding a NULL terminator, must be less than
MAX_DEVICE_ID_LEN . This constraint applies to the sum of the lengths of all the fields and any field separators in a hardware ID. For more information, see the Operations section of IRP_MN_QUERY_ID.
Obtaining the list of hardware IDs for a device
To obtain the list of hardware IDs for a device, call IoGetDeviceProperty with the DeviceProperty parameter set to DevicePropertyHardwareID. The list of hardware IDs that this routine retrieves is a REG_MULTI_SZ value.
The maximum number of characters in a hardware list, including a NULL terminator after each hardware ID and a final NULL terminator, is
REGSTR_VAL_MAX_HCID_LEN . The maximum possible number of IDs in a list of hardware IDs is 64.
Examples of Hardware IDs
Here is an example of a generic identifier for a PnP device:
root*PNP0F08
Here is an example of an identifier for a PCI device:
PCIVEN_1000&DEV_0001&SUBSYS_00000000&REV_02
