I had the UAC device enabled while running this command and all previous tests.

So even though the RIL driver is complaining about an unknow bInterfaceClass=ff and bInterfaceSubClass=ffff its what the USB device is reporting all on its own…

Also i found a post where a colleague of yours provided a screenshot of the same command for what i believe is also and EC25.
The output there is exactly the same as with mine so i guess that is correct.
