In the last month or so, I stopped being able to use my Epson
Perfection 1650 scanner from xsane. The 'scanimage' command
still works however.
I start xsane (0.86) from the command line and I can see the
largest button on the scanner flicker a bit. When I click
Start (with parameters Viewer/Color/Full range/100/1.00/0.0/0.0),
I get a dialog box that says:
Failed to start scanner: Invalid argument
I did see the large button flicker again. This seems to
be a frequently reported error message. I tried again with
SANE_DEBUG_EPSON=3 and got this:

I tried with xsane 0.88 (using an RPM I compiled myself from the
.spec file provided in the source tarball) and 0.83 but the result
was the same.
This scanner has worked very well until about a month ago. I can
provide more details if needed. Thanks.
