Scanner initialization seems to work. Then:

[epson] receive buf, expected = 128520, got = 0

I don't know the epson code nor Solaris but maybe your driver doesn't
like this big buffer? The maximum buffer size is set to 128 kB for
Solaris in sanei_scsi.c however, so it should be allright. Maybe you
want to reduce the value to e.g. 64kb just to give it a try if
everything else failse.

You will get more details when you additionally set
SANE_DEBUG_SANEI_SCSI=255.

Bye,
