[sane-devel] Canon mf3110 and CanoScan 4400f

[Nicolas Martin]

So it turns out that MF3110 does not use exactly the same Pixma protocol
as other ImageClass devices.

In order to go further into analysis, could you get a USB Snoop trace
using SnoopyPro on Windows: You can record a log trace using
SnoopyPro.exe, that you can download from sourceforge.net:

http://sourceforge.net/projects/usbsnoop/

Read instructions on SnoopyPro.exe, then try to record a scan session.

=> Select the device corresponding to the scanner, using its USB address
04a9:0x2660

There will be ~4 devices holding this address.
The scanner should be the one indicated by: "MF3110 ser"

You can recognize that it's the correct one, if you look at the frame
counter in SnoopyPro, it should increment only when MF3110 is scanning. 
This is important ... in order to avoid having huge log files filled up
with useless data!

Also, choose a **small** area to scan, otherwise, there will be huge
amount of data.

Then, Save As ... the file (in menu), zip the log and send it back to
me.
