[sane-devel] working scanner on one Ubuntu machine, fails on another

[Ed Greenberg]

I have a Fujitsu fi-4120C connected via USB to Ubuntu 11.04.  The 
scanner works fine with my Ubuntu 10.04 laptop.


When I do lsusb I get:

I do sane-find-scanner and get:
found USB scanner (vendor=0x04c5, product=0x1041) at libusb:002:013

When I do scanimage -L I get:
No scanners were identified. ...

scanadf, simple-scan and xsane all report not scanner found.

I plugged back into the 10.04 machine and all

I compared packages which contain the word sane, and all seems installed.

I'm pretty stumped.   Any suggestions?
