<pre>The xf86-input-wacom driver isn't so good at using the kernel for feature/range
detection. The first patch I linked ensures the "WCM_RING" flag is set for this
device. Without that flag, the ring valuator is created with a range of [0, 1]
like seen here (I assume as a placeholder for obscure backwards-compat reasons)
rather than the correct kernel-described range. Applying the patch does fix the
range, but there's definitely a deeper more systemic issue too.</pre>
