Just as a side note, I noticed that between 1.0.8 and
1.0.9 of Sane, the sanei_usb_write/read_bulk function
appeared to change in a fairly significant way:
1.0.8:
------
sanei_usb_write_bulk (SANE_Int fd, ...
{
...
write_size = write (fd, buffer, *size);
...
}
1.0.9:
------
sanei_usb_write_bulk (SANE_Int dn, ...
{
...
write_size = write (devices[dn].fd, buffer, *size);
...
}
When I look at sanei_lm983x.c in PLustek 0.45-TEST5, I
see the following:
...
sanei_usb_write_bulk( fd, command_buffer, &size );
...
I do get further into the debug stack when using 1.0.8
with 0.45-TEST5 than with 1.0.9. Am I correct in
assuming that 0.45-TEST5 works with 1.0.8 but not
1.0.9?
Thanks,
Marc
