First, we need to have the usb pid for this model, in order to declare
it in the pixma backend. 

The ImageClass devices use multiple versions of the Pixma protocol, so
to go straightforward to the goal, it is necessary to have a Windows
snoop log of the usb protocol it uses. 

You can use Snoopypro.exe for that. You can record a log using
SnoopyPro.exe, that you can download from sourceforge.net:


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

 => Select the device corresponding to the scanner, using its USB
address 04A9:xxxx

There should be ~4 devices holding this address.
The scanner should be the one indicated by: "MF4380 ser"

You can recognize that it's the correct one, if you look at the frame
counter in SnoopyPro, it should increment only when your 4380 is
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
