This maybe sounds too basic. Did you try to unplug and re-plug the scanner and reboot after building sane?
Reasoning - USB devices are created at plug-in/detection event. Installing a module could disrupt that. If yes, do you need scanner group membership to access the scanner. If yes, and you add yourself to the correct group, do not forget to logout for that to take effect.
