I got similar output, when I plug in that mouse with
ums0: Device USB Device, rev 1.10/0.01, addr 2, iclass 3/1
ums_attach: bLength=7 bDescriptorType=5 bEndpointAddress=2-in
bmAttributes=3 wMa xPacketSize=5 bInterval=10
ums0: 5 buttons and Z dir and a TILT dir.
ums_attach: sc=0xc1a14000
ums_attach: X   8/8
ums_attach: Y   16/8
ums_attach: Z   24/8
ums_attach: B1  0/1
ums_attach: B2  1/1
ums_attach: B3  2/1
ums_attach: B4  3/1
ums_attach: B5  4/1
ums_attach: size=9, id=3

The TILT dir is caused by the hardcoded 
sc->flags |= UMS_T;

Has anyone an idea what to do next?
I suppose I can't do anything in ums.c, as it gets the (to few) data
from another file.
