I suspect in the past the linux driver simply checked the device id and
went with that without fetching the report descriptor.
Also note qemu has a generic tablet (-device usb-tablet), so there are
probably very few users using the wacom emulation. Possibly it is
broken for quite a while already but nobody noticed ...
take care,
