[sane-devel] IRIScan pro 5

[Julien Benatar]

Hello everyone,

I am new to this mailing list so I hope that the information I provide 
are relevant.

I own a portable USB scanner called "IRIScan Pro 5", here is the 
business description: https://iriscorporate.com/products/iriscan-pro-5/. 
The drivers are only available for Windows and Mac, and interaction with 
the scanner can be done through a GUI called ButtonManager (here is the 
user manual : 
https://www.irislink.com/Documents/Image/_IrisLink2.0/support/IRIScan_pro_5/IS_ButtonManager_US.pdf). 
 From what I have seen, when the scanner starts up, the 
driver/ButtonManager seems to upload its configuration on the scanner, 
which alters its display. Then the scan can be launched from the scanner 
itself (using the "Scan" button") or using the Windows GUI.

I want to report it as an unsupported device, and give as much 
information as I can on it (see command outputs at the end of the mail). 
Also, I consider developing a backend myself, but it depends on the 
following two questions:

- Has anybody already worked on this device, or maybe a similar one? I 
plan to contact the company but maybe we already got some information on 
our side.

- Does the behavior and the USB information of this device seem 
classic/standard to anybody? I am new on this subject, but I spied on 
the USB exchanges and it seems to be very manufacturer-specific...


Thank you in advance for your answers!

Regards,

Julien
