Scanner problems

I hope this is the right list I have just attached a Canoscan 670U, it's detected by YaST and tests OK. YaST set it to the plustek driver on libusb Kooka didn't acknowledge I had a scanner attached Xsane didn't find it Running KDE 3.3 on updated SuSE 9.1 Pro Downloaded the latest Xsane from Packman. Made no difference. Any thoughts welcome TIA
