Will Microsoft provide easy way to sign INF only driver packages (WinUSB) for ARM64?

A customer has composite USB device with all functions in-box. One WinUSB, another CDT (usbserial).
They have a signed package for Win10 made years ago.
Is there a easy way (not running any **** tests) to sign their INF for ARM64?
They possibly will have to add ARM64 sections everywhere.

A related question - how to specify the latest available winusb version in the INF so that it works on all Windows versions?
In the example : https://docs.microsoft.com/en-us/windows-hardware/drivers/usbcon/winusb-installation

[WinUsb_Install]
KmdfLibraryVersion=1.11

is there a way to say “use the installed version” instead of 1.11 or any concrete number?

Thanks,
Pavel A.

If you’re changing the INF, then it’s a new package and needs to be resubmitted. If you only need Win 10, then of course you can use attestation signing.

WinUSB has shipped in the box since Vista, so you are ALWAYS going to be “using the installed version”. You don’t use the co-installers unless you need to support XP.

1.11 is the KMDF version. There have really only been two versions of WinUSB: the one that supports isochronous pipes, and the earlier one that doesn’t. The isochronous support was added in Windows 8 with KMDF 1.11. So, saying 1.11 means “use the installed version” on every system since Windows 8.

Of course, Mr. Roberts. So, if attestation signing is not available for Windows 11 - even for INF only drivers -
could Microsoft help vendors to receive arm64 signatures for drivers already signed for Win10 x64?
Has anyone heard of such plans?

Lack of native arm64 driver is not a show stopper, if the “update driver” procedure via Device Manager still works on win11; I cannot check this without a compatible machine.

To my knowledge, no one has even hinted this might happen.
