Hello,
is the C source code of your porting attempt available?
I didn't see it at http://www.juergen-ernst.de/info_sane.html
Yes, C source is available. Months ago I must have been removed the link.
Here it is again, see item Help second paragraph.

Hi!
Can someone help me with that SANE backend for Canon LiDE 600?
My current stage of development is a perl script which is able to do a
scan at 300 dpi.
http://www.juergen-ernst.de/info_sane.html
I'm not very familiar with the SANE framework and it's very complicated
for me to do the C stuff.

what scanner did you use that produces such poor calibration?

Hi!
I'm trying to write the backend for Canon LiDE 600F and now I'm stuck
with sanei_usb_read_bulk. I tried 10 hours but I don't understand how to
get sanei_usb working with bulk_read. Can somebody help me out?
Here are some details:
Canon LiDE 600F is similar to Canon LiDE 70. I checked this
Oops.
The bulk read and write should have been written this way:
status = sanei_usb_write_bulk (0, setup_buffer, count);
...
status = sanei_usb_write_bulk (1, setup_buffer, count);
...
status = sanei_usb_read_bulk (1, data, count);
First endpoint 0 then 2 times endpoint 1.

Hi!
I managed to solve the problem.
Here it is:
Canon driver sends a dummy bulk write as shown in the log. It only
produces errors and I think it's only for delaying bulk reads. We can
omit that and use a fix delay of 1 ms instead.
Sanei_USB sets the right endpoints. I can read and write data on
As reported from sane project Canon LiDE 70 has the same chip (Philips
CP2155BE) as Canon LiDE 600F inside. It was supposed that they will
behave mostly the same.
Now I got reports from users with Canon LiDE 70 and my perl scripts for

Can whatever you're doing for the 600F be applied to the 500F?
I don't think so. 600F and 500F sounds to be nearly the same but
internal they are not. 600F has 2 USB endpoints and 500F has 3 USB
endpoints. The protocol is also very different. 500F uses control
Hi!
Did somebody know why a scanner needs 5 gamma tables?
In calibration I found 5 tables which were set before scanning is
invoked. I first thought I would find 3 tables for R,G and B.
But why are there 5 ???
Does somebody know?

Hi!
Scanner protocol of Canon LiDE 600F is very high level. With a
structural analysis it is possible to see functional blocks of driver
code. With my knowledge till now I should be able to program a perl
script in a couple of days to do a first low resolution scan.
Can somebody confirm that

The LiDE 70 is a gl841 based scanner, and those are dumb scanners with

I am wondering. According to

Hi!
I'm working on backend Canon LiDE 600F.
Seems similar to Canon LiDE 70.
Is someone working on Canon LiDE 70?
We could join our work.

Hi!
I have to report a first success with a CanoScan LiDE 600F.

picture from a new telescope :-)
I wrote a perl script to access the scanner via Device::USB.
After formatting the log (I made with benoit's usbsnoopy) I replayed

complete a small scan with a usb sniffer to log the traffic on the usb bus for

That may allow identification of the protocol.

Hi!
Unfortunately yesterday I bought a Canon CanoScan LiDE 600F.
Is anyone working on a backend to that scanner yet?
If yes I want to join.
If not I want to start programming a backend.
