USB Input Device incorrectly listed as NPU device on x64/non-Copilot+ PC #10
Description
Description
On x64 systems without an NPU (non-Copilot+ PCs), the diagnostics incorrectly identifies a "USB Input Device" as an NPU device with "Estimated Performance: Unknown".
Steps to Reproduce
- Run the application on an x64 system without a dedicated NPU
- Run diagnostics
- Check the NPU/AI device section
Expected Behavior
- Non-Copilot+ PCs should show "No NPU detected" or similar
- USB Input Devices should not be classified as NPU devices
Actual Behavior
- Shows "USB Input Device" as an NPU
- Shows "Estimated Performance: Unknown"
Environment
- Architecture: x64
- Hardware: Non-Copilot+ PC (no NPU)
Root Cause (Likely)
The NPU detection logic may be using a device class or interface GUID that also matches USB HID devices, or the WMI query is too broad.
