Comment 5 for bug 379743

As of today it seems the problem is yet to be fixed. I'd like to summarize some of what I've collected so far. (Non-expert view).

Some persons using HP printer-scanner-copier devices found the printer working well, but the system not recognizing the scanner. In my & other cases, it was HP-915, first noticed on Ubuntu Jaunty in Apr-May 2009 when the new version of the OS was released.

(This is marked solved but it was not solved.... as you can see)

Other Linux OSs released at the same time also have the same problem. I confirm this for Mandriva 2009 Spring, Debian Lenny, Fedora 11 (all gnome).

(another poster on debian: could someone with current Ubuntu or other distros try this out & comment? )

The problem still persists
a)with karmic (ubuntu), Mandriva 2010 (reports on the net)

b)with Fedora 12 (personal experience)

(but, ok, this person had things working with Jaunty)

If I go back to Intrepid or Hardy the device works perfectly. (am presently on Intrepid for this single reason).

(these gentlemen got things working in a very convoluted way)

And finally, (I think, Important!!!), there's this post right on front of the Xsane webpage (URL below)
http://www.xsane.org/
I have noticed this posting there since Apr 2009 and it's still there. I think the gist is that newer versions of sane are not compatible with sane backends. ( don't remember if I tried this in May 2009. Now, the version of sane-utils on my Intrepid laptop (where scanning is fine) is 1.0.10-6ubuntu1 )

So, putting it together,
1)Many people who were previously fine with their HP printer-scanners have been having problems with (only) scanning since Apr-May 2009 to date.
2)This is a problem with Ubuntu, Fedora, Debian, Mandriva, since Apr-May 2009.
2)The problem may be with new versions of sane not being compatible with sane-backends (please correct (and forgive) me if my interpretation is wrong.

Now could technically able persons take over, and please help. I hope the above stuff may be useful. I really, really want to have karmic.

Thanks
