Comment(by zelegolas@…):

 > I'm surprised to hear that your DocuMate262i stopped working as it looks
 like support for it was only added to the avision backend between versions
 1.0.21 and 1.0.22

 I know. I applied by myself the patch you mention at "''Page (in french)
 about using the DocuMate262i with SANE''" and it was working perfectly :)

 Now when I run this command:
 {{{
 scanadf --source "ADF Duplex" --mode Gray --output-file
 "DocuMate262i/Page-%04d.ppm" --start-count 1
 }}}

 After a few second it's return:
 {{{
 scanadf: sane_read: Error during device I/O
 Error during device I/O
 Scanned 0 pages
 }}}

 And if I try again I have this message:
 {{{
 scanadf: sane_start: Document feeder jammed
 Document feeder jammed
 Scanned 0 pages
 }}}

 And it's normal because my paper it's blocked on the device.

 Because the modification on the backends layer it's very small and because
 it's exactly the one that i applied by myself i'm not sure if the issue
 come from sane-backends. It's may be an issue with sane-frontends or the
 usb layer. But I don't know how I can check that. I will read your links
 (again) and see if I can do something with it... I you thinks about some
 informations, tricks or anything could be help just let me know.
