I'm having difficulty getting sane going on Solaris 8 (x86)
with an Epson Perfection 1200S scanner on an Adaptec scsi card.
I was having odd lock-up problems when using the Schilly SCG
driver (which I had been using since Solaris 2.6 days) 
so I switched to the built-in SGEN driver in the hope that 
things would get better.  I'm running sane-backends-1.0.8.

Here's the symptoms:
I can run scanimage with the default resolution (50) fine;
but if I want more detail than that, if I put a "--resolution"
option on there, half-way through the scan I get:

$ scanimage --mode gray --resolution 72 >out
scanimage: sane_read: Error during device I/O

[500 lines of debug output that goes here is
available at http://www.ingenotech.com/tmp/sane_debug.txt]

At this point it is stuck in a forever loop.

I have to CTRL-C scanimage twice to get out of that and the scanner
is then locked-up with a red light on.  scanimage --list-devices
no longer acknowledges its existence.  But with SANE_DEBUG_EPSON=128
it clearly IS finding the scanner.

[Again http://www.ingenotech.com/tmp/sane_debug.txt contains details]

If I cycle the scanner power and wait a bit it will work again at the
default resolution (50), with anything higher it ends up in a spin

Hope someone can help me with this, I really like the idea of being
able to use my scanner in Solaris :-)
