[PD] [hid] crashing with segmentation fault

[Christian Klippel]

hi all,

be aware that mice usually _only_ give relative coordinates.

as for tablets, they usually allow to switch between absolute and relative 
mode. if the tablet reports realtive events only, its probably just set to do 
so. 

iirc, wacom tablets allow the toggling between abs/rel mode with one of their 
"function keys" at the top row of the tablet. otherwise you may need a small 
tool to set it to abs mode.

maybe you had id connected to something that has set it to relative mode 
once .....

greets,

chris
