When I disconnect & reconnect it, I get lots of stuff like this as the 
pointer moves about the screen:

ums_intr_callback: sc=0xffffff00015ae800 actlen=8
ums_intr_callback: data = 00 00 00 00 ff ff 00 00
ums_intr_callback: x:0 y:1 z:0 t:0 w:0 buttons:0x00000000
ums_intr_callback: sc=0xffffff00015ae800 actlen=8
ums_intr_callback: data = 00 00 00 00 fc ff 00 00
ums_intr_callback: x:0 y:4 z:0 t:0 w:0 buttons:0x00000000
ums_intr_callback: sc=0xffffff00015ae800 actlen=8
ums_intr_callback: data = 00 00 ec ff d5 ff 00 00
ums_intr_callback: x:-20 y:43 z:0 t:0 w:0 buttons:0x00000000

But nothing at all when it hasn't initialised properly.
