Yes you are right.
Seems that xscanimage (Scanner: epson GT-9500) has the same problem.
It crashes with SIGSEGV while reading the epson+_b0t6l0.rc near "Flatbed".
it crashes in sanei_scsi.c line 3609 (CVS)
memcpy (aspi_buf, (char *) src, srb.u.cmd.data_len);
because aspi_buf is NULL at this moment.
If I comment out reset(s) line 3356 in epson.c /* necessary for perfection
1650 */
xscanimage works again.
What would be the correct solution?
Perhaps the scanner-device has to be opened before
sending reset()
Is Perfection 1650 USB only?
