I have since called tech support. While the guy was very freindly / helpful (tried to be helpful anyway). He had no idea how to fix it.
In the end all he could come up with was, try using xp with something other then SP3 (in fact he suggested trying all without service packs aswell as with SP1 and SP2). I suspect this was more about getting me off the phone because both him and his suprevisor/level 2 tech, had run out of ideas.
Unfortunately for him I had already tried every thing he could think to try. Which I will run throught quickly.
I have tried: Multiple computers (physically different hardware 4 or them, including two different brands), different USB ports within those computers. I have tried the suggested SP2 (I did not try SP1 or no SP at all. As the box specifically states XP SP3 as a 'requirement')
I have tried both the web version and CD version of the driver (although I believe these are both the same version anyway)
Also, I have successfully installed and used this under both Linux (Ubuntu) and Win7.
Does anybody actually have this, and are using it succsessfully with XP?
Thanks
