problem using Wacom tablet with XFree 4.0.3

Hi. 
I'm having problems getting my Wacom Intuos USB graphical tablet to work 
with XFree 4.0.3. 
I have uses the howto as my guide and I got it to work with gpm but when 
running X I get a lot of these errors in the logfile:

Wacom write error : Unknown error 1007
Wacom unable to read first byte of request '~#' answer after 3 tries

later on the write error changes to Unknown error 1013

sometimes I also get other numbers but 1007 seems to return frequently.

So what does this mean (unknown error isn't very helpfull) and what do I 
do about it?

Thanks, Bas
