Simple scan should not recognize webcam as scanning device

[moimael]

Hi,

When I open simple-scan without scanner attached or powered on, I don't get the infobar message saying so. Instead my webcam is detected as a scanning device. It is not an expected behaviour. Particularly when you hit scan all pages, then scanning will go in an infinite loop.

Webcam should not appear in simple scan. It is rather cheese job.

Thanks !

For some reason SANE detects webcams as scanners because they provide some features scanners also provide. while this is an interesting feature, i don't think it should be enabled by default.

currently Simple Scan does nothing to discriminate against webcams but accepts any device SANE offers. maybe we can change it at the application level...

I made a very simple patch that should only detect scanner devices.

Here is the doc behind the logic : http://www.sane-project.org/html/doc011.html (section "4.2.8 Device Descriptor Type")

Would be cool if it could be integrated in 3.12 ! :)

The patch is quite old now, can it be reviewed ?

Thanks !
