[sane-devel] Big problem with fi-5650c under linux

[guus]

Hello All,

I have bought a fi-5650c scanner to replace a fi-4120c.
In addition, I have a new linux server.

The new scanner is fine, it works ok when I connect it instead to my old server.
The new server is also fine: the old fi-4120c scanner works ok on the new server.

The problem is that the new fi-5650c scanner does not operate when I connect it to the new server: 
scanner is recognized ok and the adf starts feeding but stops halfway, before any real scanning:

Here is an excerpt from the debug output (full text below):

[fujitsu] sense_handler: start
[fujitsu] Sense=0x5, ASC=0x26, ASCQ=00, EOM=1, ILI=0, info=00000000
[fujitsu] Illegal request: invalid field in parm list
[fujitsu] Offending byte is 00
[fujitsu] do_scsi_cmd: return 'Invalid argument'

This looks like a software bug, because the scanner functions ok.
I would report it as a bug, if I knew more about the cause.

My old server:
- kernel:  2.6.8-2-686
- cpu:     Intel Celeron
- scsi:    LSI Logic / Symbios Logic 53c810 (rev 23)
- libsane: 1.0.18-3

My new server
- kernel:  2.6.18-4-amd64
- cpu:     Dual Core AMD Opteron
- scsi:    Adaptec AHA-7850 (rev 03)
- libsane: 1.0.18-6

I am not sure where to look; my choices seem limited and/or futile:
- I have a k7 server that I could try, but what would be the point?
- I could try swopping scsi cards, but that is probably futile
- USB is not an option for this scanner, according to libusb.

Unfortunately, the reported scanner dialogues have really changed from sane 1.0.18-3 to 1.0.18-6

The most likely cause is some change in the sanei area, because the fujitsu backend is not changed, 
according to a brief inspection of cvs.

Most likely short term solution: fall back to 1.0.18-3
But how can I retrieve the 1.0.18-3 sources from cvs???

Another minor problem of the fi-5650 under sane is that each pixel row is shifted by one pixel 
relative to the previous row, making the output image look slanted. My own software can compensate 
for this, so it is not a big problem. However, it may be related (who knows).

Thanks for any help.
Guus.
