In Windows 10, some IDs that previously appeared in the Hardware IDs list now appear in the list of Compatible IDs. R(2) is the two-character revision number.Ĭ(2) is the two-character base class code from the configuration space. As specified in Publishing restrictions, 0000 and FFFF are invalid codes for this identifier. N(4) is the four-character PCI SIG-assigned identifier for the vendor of the subsystem. S(4) is the four-character vendor-defined subsystem identifier. As specified in Publishing restrictions, 0000 and FFFF are invalid codes for this identifier.ĭ(4) is the four-character vendor-defined identifier for the device. V(4) is the four-character PCI SIG-assigned identifier for the vendor of the device, where the term device, following PCI SIG usage, refers to a specific PCI chip. When the Plug and Play (PnP) manager queries the driver for the hardware IDs of a device, the PCI bus driver returns a list of hardware IDs in order of increasing generality. The following is a list of the device identification string formats that the PCI bus driver uses to report hardware IDs. To list IDs on Windows, use devcon hwids *. You can find a list of known IDs used in PCI devices at The PCI ID Repository.
