USB-C multiplexes multiple types of signals through a single port. The UCSI framework coordinates when a port should transition from carrying standard USB 3.2 data to carrying or Thunderbolt/USB4 data protocol streams. 3. Cable Orientation and Error Reporting pnp0ca0

Users on Linux sometimes encounter issues where USB-C charging or display output fails because the BIOS "hides" the PNP0CA0 device from non-Windows operating systems.

Because PNP0CA0 is an ACPI device, its functionality depends on the BIOS, which tells Windows how to map the hardware.

To monitor or control the fan speed on a Linux system with an ACPI fan device: As with any hardware component, PNP0CA0 can sometimes

If your BIOS/firmware is newer than your OS, it might show up as an "Unknown Device" with the hardware ID ACPI\PNP0CA0 . How to Fix Driver Issues
