ERROR_GPIO_VERSION_NOT_SUPPORTED

Unsupported GpioClx client version

ERROR_GPIO_VERSION_NOT_SUPPORTED is Windows system result 15323 (0x00003BDB). The registration data is being interpreted against a different DDI version than the installed framework accepts.

ERROR_GPIO_VERSION_NOT_SUPPORTED is a compatibility result. The Version and Size pair supplied by the GPIO client must match an interface version available on the target Windows release.

Where this value belongs

  • ERROR_GPIO_VERSION_NOT_SUPPORTED can be observed when a driver built for a newer GpioClx DDI loads on an older system.
  • ERROR_GPIO_VERSION_NOT_SUPPORTED can be observed when a registration packet uses a version constant with the wrong structure size.
  • ERROR_GPIO_VERSION_NOT_SUPPORTED can be observed when shared source selects the wrong target-version branch.

This code does not show that GPIO hardware is defective. It shows that driver and framework cannot agree on the client contract version.

Common interpretation mistakes

  • ERROR_GPIO_VERSION_NOT_SUPPORTED is mishandled when only the Size field is changed while the Version remains new.
  • ERROR_GPIO_VERSION_NOT_SUPPORTED is mishandled when the driver assumes a newer OS feature is always present.
  • ERROR_GPIO_VERSION_NOT_SUPPORTED is mishandled when conditional compilation selects a mismatched packet layout.
  • ERROR_GPIO_VERSION_NOT_SUPPORTED is mishandled when the unsupported version is hidden by a generic installation error.

Diagnostic sequence

  1. Log Version and Size before GPIO_CLX_RegisterClient.
  2. Compare the target OS with the DDI version used at build time.
  3. Inspect conditional compilation and SDK header versions.
  4. Verify all callbacks required by the selected version.
  5. Test the binary on the oldest declared supported Windows build.
  6. Reject unsupported combinations before device hardware is touched.

Evidence worth keeping

  • For ERROR_GPIO_VERSION_NOT_SUPPORTED, preserve registration Version and Size.
  • For ERROR_GPIO_VERSION_NOT_SUPPORTED, preserve WDK and SDK build versions.
  • For ERROR_GPIO_VERSION_NOT_SUPPORTED, preserve target OS build and architecture.
  • For ERROR_GPIO_VERSION_NOT_SUPPORTED, preserve selected callback layout.
  • For ERROR_GPIO_VERSION_NOT_SUPPORTED, preserve driver INF support declarations.

For ERROR_GPIO_VERSION_NOT_SUPPORTED, build metadata belongs in the support bundle because the same source can produce different packets under different WDK targets.

Correct handling and recovery

Build or select a driver interface version supported by the target OS and initialize the exact matching registration structure.

A device restart does not change DDI compatibility. Retry only after installing a compatible driver or supported operating-system version.

Difference from nearby values

ERROR_GPIO_INVALID_REGISTRATION_PACKET means the chosen packet is invalid. Code 15323 specifically identifies that the requested interface version is unsupported.

Practical scenario

A universal driver accidentally ships a packet version introduced after the product’s minimum OS. Testing on that minimum build returns 15323, leading to a corrected target-version guard.

Implementation guidance

Declare and test the minimum supported OS explicitly. Keep Version and Size initialization adjacent and cover every target branch in CI.

For code 15323, record gpio_version_requested, gpio_packet_size, gpio_os_build, gpio_wdk_version, and gpio_minimum_supported_build.
