Thanks for your suggestion Charlie, but the user and group of the device are no longer being set to root:scanner anymore for some reason but to root:root. In that case it doesnt matter if the user is in the sacnner group: it does't have any access to the device anyway.... Rebooting and crossing my fingers didn't change this situation ;-)
It can't be too difficult of a problem because root can scan fine using kooka.
