[sane-devel] Error when reading from Fujitsu fi-5120c

[Matthew]

I'm using Ubuntu 6.06 with all the latest updates and Sane backend 
1.0.18 compiled from source along with Xsane .0991.

When I try to scan using scanimage or xsane either as root or as normal 
user I get the following error.

"Error during read: Error during device I/O."

I've read just about every instruction on setting up Sane and so far I 
can't get it to work.  I did get it to work once, but then it stopped. 
I believe I manually changed the usb permissions.  I've tried to figure 
out the hotplug stuff, but so far I've failed at everything.

Can anybody tell me what I'm doing wrong or not doing?
