Questions tagged [device-instance-id]

Use this tag for questions about Microsoft Device Instance IDs. Example of a Device Instance ID is `PCI\VEN_1000&DEV_0001&SUBSYS_00000000&REV_02\1&08`. It is a device identification string supplied by the Plug and Play Manager.

A device instance ID is a Windows system-supplied device identification string that uniquely identifies a device in an operating system. The Plug and Play (PnP) manager assigns a device instance ID to each device node (devnode) in the system's device tree. A device instance ID is persistent across system restarts.

An example of a Device Instance ID is:

PCI\VEN_1000&DEV_0001&SUBSYS_00000000&REV_02\1&08
