[sane-devel] Problems with Epson 636U

[James O'Test]

Thank you for the quick reply. I followed your advice and generated the log file for you.

I ran xsane, it started up, I tried to aquire a preview and it hung.

Please, let me know if there if anything else I can do to help track the
problem down. 

Thank you.
Jim

: Set the debug variable (depending on your shell you may

: export SANE_DEBUG_EPSON=128
: xsane > /tmp/scan.log 2>&1
: 
: You can use any other frontend with the same output
