  Hi!

  I'm working with Linux, Kernel 2.2.12 and tried to get a Tamarack
  Artiscan 12000C SCSI-Scanner working with Sane 1.0.4.

  Both scanimage (e.g. with --test) and xscanimage come up with the
  following error:

  scanimage: sanei_scsi.c:3707: sanei_scsi_cmd: Assertion
  `src_size == cmd_size' failed.

  This results from the call

  status = sanei_scsi_cmd (s->fd, &cmd, sizeof (cmd)+2, buf,
  &nbytes);

  in line 565 of backends/tamarack.c. (That `+2' seems a bit strange to
  me...)

  Searching the mailing list archive resulted in some mails where the
  sanei_scsi_cmd function was modified because of problems with command
  sizes and the sg driver. Yet I don't know very much about Sane
  internals to get a clue what exactly is wrong in my case.

  Could anybody provide me with some information what I could do to fix
  the problem? -> Patches, Upgrades?

  Thanks in advance for your help,
  FJ
