Fujitsu ScanSnap ix500 in Ubuntu 12.04

sane-find-scanner found scanner (vendor=0x04c5, product=0x132b)

Nothing else seems to find the thing. scanimage -L returns "No scanners were identified" same with gscan2pdf

I think my updates are current, I've tried rebooting, etc. How do I get this scanner to work?

Getting ready to try monkeying around with fujitsu.conf (which doesn't yet show this product) and dll.conf, which I am not really competent to do...
