[font=Tahoma]Sorry for delayed response, I was tied up with errands yesterday.
It seems you've done everything right. I'm afraid I have no definitive answer, maybe, try to toggle fullscreen in GIMP (F11) and see if that makes GIMP recognize the tablet. If you still have GIMP on your old laptops with which your tablet worked, try to copy configuration files from GIMP folder to your new set:
controllerrc, devicerc. Rename temporarily your current config files (eg, controllerrc.old, etc) and go from there. Hope this helps.
You might want to check these threads on gimp-mailing list. Some answers to users with similar problems may be of some help.
