scanimage: no SANE devices found



this is with only the 636 plugged into my PCI USB card.
It seems to indicate that another process has claimed exclusive 
access of the device.
But I have no apps running other than Finder and Terminal.
sane-find-scanner does find the 636.
any help/ideas would be appreciated.

Thanks,

Fritz
