Huawei UMTS USB dongle identified as scanner

[Rolf Leggewie]

On an uptodate precise system Huawei USB UMTS dongles are incorrectly identified as scanners. I tried this with two different, albeit very similar dongles.

$ sane-find-scanner |grep -v -e '#' -e ^$

This seems to affect Debian as well: http://forums.debian.net/viewtopic.php?f=30&t=84137

No, sorry, the above link links to a problem with a scanner rather than a USB dongle

Ads20000, if you are referring to http://forums.debian.net/viewtopic.php?f=30&t=84137 then you did not look closely enough. Specifically at device 003:005. Have another look. Besides, it's all over other reports in Launchpad as well, where you can see this happening.

sane-find-scanner identifies devices that *could* be scanners. This is by design. Please see
https://gitlab.com/sane-project/backends/-/issues/575

Message has been improved upstream to say "found possible USB scanner".
