Warnings using MSYS2 clangarm64 compiler

[mcuee]

Just got an Acer Aspire 14 AI laptop 2025 model with Qualcomm X1 26100 CPU and running Windows 11 ARM64 25H2.

There are some warnings when building using MSYS2 clangarm64 compiler. No issues when using MSYS2 ucrt64 gcc 16.1.0.

unable to open device

[mcuee]

HIDAPI works fine under this Windows 11 ARM64 machine.

Only issue is that Zadig does not work so that I cannot test libusb backend (not officially supported anyway). I cannot switch the system HID driver with WinUSB driver under WIndows 11 ARM64, unlike the normal x86_64 machine.
