Unfortunatly, Kevin patch does *not* apply on SANE 1.0.1.
While waiting for him (four long days :), here is the change
he suggested me to have it work:

In 'sane_get_parameters' routine, replace:

status = open_scanner (pss);
CHECK_STATUS (status, me, "open_scanner");

/* fetch the latest parameters */
status = inquiry (pss);
CHECK_STATUS (status, me, "inquiry");

close_scanner (pss);

with:

if (pss->state == ST_IDLE) {
status = open_scanner (pss);
CHECK_STATUS (status, me, "open_scanner");

/* fetch the latest parameters */
status = inquiry (pss);
CHECK_STATUS (status, me, "inquiry");

close_scanner (pss);
}
else {
DBG(DL_INFO, "NOT doing an inquiry to get scanner parameters\n");
status = SANE_STATUS_GOOD;
}

That should do the trick.

Happy scanning,
