[sane-devel] Please Help with Epson Stylus CX-5800

Sun May 7 02:25:18 UTC 2006

Hello,

I just bought an Epson Stylus CX-5800 All-In-One machine the other day 
that I'm hosting on my network.  I have printing working fine at this 
point, but I can't seem to get the Sane Epson backend to talk to this 
new machine.  I have the USB device information explicitly called out in 
the Epson configuration file and have verified that the Epson driver is 
being loaded/tested.  It appears to be some kind of protocol error or 
something.

I could use some help in getting this going.  I'm including an excerpt 
from the logged information that seemed relevant.  I'm more than willing 
to collect more debugging information.

This is an Ubuntu Dapper installation with kernel 2.6.15.
Sane version 1.0.17

Thanks in advance for any help you can give me,
Craig
