ACPI (Advanced Configuration and Power Interface)

Unlike common PNP IDs such as PNP0500 (a standard serial port) or PNP0C09 (an embedded controller), PNP0CA0 does not correspond to a legacy ISA device. Instead, it falls under the umbrella of the specification. ACPI is the modern standard that allows an operating system to communicate with the motherboard to discover hardware, perform power management, and control thermal zones. In this context, PNP0CA0 is the ACPI Hardware ID for a Generic Container Device . pnp0ca0

appears to be a hardware device identifier string in the style of ACPI/PCI/Plug-and-Play naming used by operating systems (especially FreeBSD, Linux, or BSD-family kernels) to label devices. Below is a concise explainer and how it’s typically used.

The hardware ID refers to the UCM-UCSI ACPI Device , which is the software interface for managing USB Type-C connectors on a computer. Technical Role
