Story: WinRT backend for Windows

[Youw]

Current Windows backend is WinAPI based. There is also an alternative - WinRT API, and it actually uses a different implementation.

More discussion about it: #282. Having an alternative backend might be useful in the future. Leaving this ticket to follow up on it if someone ever gets to finish it. ~Some attempt to move in this direction:~ ~https://github.com/LeeChunHei/hidapi~ UPD: see next comment.

A general recommentation is to have this backend implemented in C++, due to way simpler implementation, when it comes to WinRT, compared to C.

[Youw]

I have had a little "weekend codding" session, and tried to implement the WinRT backend implementation for HIDAPI, and here is the result: https://github.com/libusb/hidapi/compare/winrt

I'm not even sure if it worth making a PR into master as of yet, but here are some statements about the implementation:

• it is written in pure C++/WinRT, i.e. it can be use in Windows Store applications (I believe the WinAPI HIDAPI backend uses some APIs that are not available from UWP/Windows Store environment);
• this is an implementation from scratch; no existing code from WinAPI backend is used/copied (I guess hid_error looks very familiar, but that's not the point);
• it inherits all of the limitations of the Windows.Devices.HumanInterfaceDevice subsystem as of this moment, e.g.:
  • Serial Number is not available;
  • Manufacturer String is not available;
  • Vid/Pid/UsagePage/Usage - available only for devices that can be opened, i.e. not availbale for Keyboars/Mouses/etc. (even though enumerated and "Name" is available);

And I wasn't able to test it intensively, keeping it in the branch for now. Just in case someone would want to play with it.

• it is written in pure C++/WinRT, i.e. it can be use in Windows Store applications (I believe the WinAPI HIDAPI backend uses some APIs that are not available from UWP/Windows Store environment);

The Microsoft Store is no longer restricted to UWP: https://developer.microsoft.com/en-us/microsoft-store/desktop-apps

[Youw]

I believe there're still restrictions on WinAPI usage (and HIDAPI/WinAPI doesn't follow them). I'll search for link with description later.

This seems to work pretty well, tested under Windows 11 with VS2022.

Edit: this is not correct. So I deleted the output.

This seems to work pretty well, tested under Windows 11 with VS2022.

I do not believe you've actually used the winrt backend. You need to pass -DHIDAPI_WITH_WINRT=ON and run the hidtest-winrt executable.

Here is the output for the draft WinRT backend. Other than the limitations mentioned in the first post, I can see that product string is also not correct when there is none. Now it uses the computer name.
