Test results

• Direct MinGW C++17 compile/run verification passed for test_c_api.
• Direct MinGW C++17 compile/run verification passed for test_device_model.

Concerns

• CMake/CTest verification remains unavailable because cmake is not installed or not on PATH.
• libusb-enabled enumeration path is implemented under conditional compilation but not compiled in this environment because MAG160C_HAS_LIBUSB=0.
• Generated local executables build_task4_c_api_test.exe and build_task4_device_model_test.exe exist from substitute verification.

Self-review notes

• Endpoint pair selection returns first bulk IN and first bulk OUT.
• No-libusb list_devices path returns MAG160C_ERR_UNSUPPORTED and clears output pointers/count through the C ABI.
• C ABI device list allocation uses new[] and free uses delete[].
• Public device info struct uses only C-compatible fields.

Fix report: libusb-enabled list_devices test compatibility

Test results

• Direct MinGW C++17 compile/run verification passed for test_c_api.
• Direct MinGW C++17 compile/run verification passed for test_device_model.

Self-review

• test_c_api now expects MAG160C_ERR_UNSUPPORTED only when MAG160C_HAS_LIBUSB is 0.
• test_c_api accepts MAG160C_OK and frees any returned device list when MAG160C_HAS_LIBUSB is 1.
• CMake now propagates MAG160C_HAS_LIBUSB to test_c_api via MAG160C_HAS_LIBUSB_VALUE.
