Ah, that was it, thanks!

Now the driver probably works, but I think there are two problems. The
first problem is that if I have the ums driver configured in my
kernel, it'll attach to the Graphire3, and wsmouse attaches to that. I
then no longer have a /dev/uhid0 to call USB_GET_REPORT_DESC on. If I
use /dev/wsmouse1 instead, it returns an "Invalid ioctl for device"
error. It looks like wsmouse doesn't recognize the ioctl, so it calls
ums_ioctl. ums doesn't recognize it either, so it returns EPASSTHOUGH.
I don't know what EPASSTHROUGH does, but it doesn't seem to be passing
it up to uhid, which would know what to do with the ioctl. I guess
this one belongs more on tech-kern than x11 though (I'm touring all
the mailing lists :) For now, I've commented ums out of my kernel:

uhidev0: WACOM CTE-430-UV3.1-4, rev 1.10/3.14, addr 2, iclass 3/1
uhidev0: 3 report ids
uhid0 at uhidev0 reportid 1: input=4, output=0, feature=0
uhid1 at uhidev0 reportid 2: input=7, output=0, feature=1
uhid2 at uhidev0 reportid 3: input=0, output=0, feature=1

But the main problem is that the driver doesn't seem to support the
Graphire3; when I start X, it now complains "/dev/uhid0 has no X, Y,
or In_Range report" (same complaint if I use uhid1 or uhid2). Looks
like the Graphire3 doesn't use the standard USB Digitizer reports?

I see that there's code in sys/dev/usb/uhidev.c to override the report
descriptor for the original Graphire, so I tried using the same
override for the Graphire3, but that only made uhidev0 reportid 1 not
show up at all:

uhidev0 at uhub0 port 2 configuration 1 interface 0
uhidev0: WACOM CTE-430-UV3.1-4, rev 1.10/3.14, addr 2, iclass 3/1
uhidev0: 3 report ids
uhid0 at uhidev0 reportid 2: input=7, output=0, feature=2
uhid1 at uhidev0 reportid 3: input=0, output=0, feature=2

So... am I out of luck? :)
