Well, this uhid0 device looks like a USB mouse. It explains :
1) why the device attaches as ums0 in the kernel
2) why the usbtablet driver doesn't grok it (it look for an In_range
   usage in one of the inputs, which is missing there).

You should be able to use it under X by letting the kernel attach it
as ums0 and configure an InputDevice section in XF86Config for
/dev/wsmouse1

This hid looks more like a digitizer, however the Microsoft pages are
of course not what the generic USB tablet driver expects. I don't have
a graphire 3 available to try to decrypt the data in those pages.

FYI, here's how a graphire 2 looks like:

Collection page=Digitizer usage=Digitizer
Collection page=Digitizer usage=Digitizer
Input   size=1 count=1 page=Digitizer usage=Touch, logical range 0..1
Input   size=1 count=1 page=Digitizer usage=Barrel_Switch, logical range 0..1
Input   size=1 count=1 page=Digitizer usage=Barrel_Switch, logical range 0..1
Input   size=1 count=1 page=Digitizer usage=Invert, logical range 0..1
Input   size=1 count=1 page=Digitizer usage=Transducer_Index, logical range 0..1
Input   size=1 count=1 page=Digitizer usage=In_Range, logical range 0..1
Input   size=16 count=1 page=Generic_Desktop usage=X, logical range 0..10206
Input   size=16 count=1 page=Generic_Desktop usage=Y, logical range 0..7422
Input   size=16 count=1 page=Digitizer usage=Tip_Pressure, logical range 0..511
End collection
Feature size=0 count=1 page=Digitizer usage=Undefined, logical range 0..511
Total   input size 7 bytes
Total  output size 0 bytes
Total feature size 2 bytes
