= -EBUSY (Device or resource busy). This often means:
For kernel developers, PRP0001 is part of the "Unified Device Property API." It allows you to define device properties in ACPI using a special _DSD (Device Specific Data) object. This permits the kernel to match the device to a driver using a compatible string (like atmel,24c256 ) even though it's on an ACPI platform.
If you see messages regarding PRP0001 in dmesg (e.g., during driver probing or failed ACPI initialization), consider the following, as discussed in StackOverflow :
For an I2C device, ensure the I2C controller driver is bound:
This example would indicate that the device is a set of GPIO keys (power buttons, lid switch, etc.).
Device (TDA0) Name (_HID, "TDA7802") // Official vendor ID Name (_CID, "PRP0001") // Allows fallback to DT matching Name (_DSD, Package() ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () Package (2) "compatible", "st,tda7802" ,
or power management features that lack official Windows-signed drivers. Chromebooks : It often points to specialized components like specific LED controllers How to fix it Steam Deck users : Ensure you have installed the latest APU and SD Resources drivers official Steam Deck Windows Resources page Chromebook/Other : Check the manufacturer's support site (e.g., HP Support ) for specific chipset or "Serial IO" drivers. Linux users : This is usually handled automatically by the kernel's acpi_scan_handler Google Groups Are you seeing this ID in Windows Device Manager on a specific handheld or laptop?
If present, you’ll see the device’s compatible string and its driver binding.
