iomega zipcd usb, not recognized

Its a Iomega zipcd 650... worked fine for a year, and now it's not
recognized. I tried different wire, different ports, changing some settings
in the extensions, that iomega advised, and now I don't know what else to
do. It's a imac g3 running os x as far updated as allowed below Jaguar. and
it has 9 too. And so maybe there's hope here... J
