Happy New Year to everybody,

I've already posted an announce that alternative eSCL backend is available:


But because I've got no official reaction, I decided to gently remind 
about myself.

Thank to Till Kamppeter, for his patience, time and very professional 
feedback, issues with his HP DeskJet 2540 were solved. It was a very 
problematic device, because it's XML parser appeared to be broken, which 
nobody would ever suspect. We also found a bug in ippusbxd and Till now 
works on it, so scan via IPP-over-USB also works. And later I've 
received a report that my backend works with HP ENVY 4500.

Also, from my own experience, it works with Kyocera ECOSYS M2040dn, 
which sane-escl doesn't. This is important issue, because unlike Cannon 
and HP, Kyocera doesn't provide even a low-quality closed-source network 
drivers for linux.

My backend is very mature and it implements many features, missed in 
sane-escl, such as ADF support (simplex, duplex, multipage), 
sane_cancel() and so on.

Unfortunately, I'm not an organization, but rather a physical person, so 
I don't have an access to great variety of hardware to test with. This 
is why I ask the community to help me with testing my backend on a 
hardware not listed in README.md

I'm especially interested in testing on eSCL-capable photo cameras, if 
there are any, because as far as I know, none of existing opensource 
eSCL implementation works with them.


	Wishes, Alexander Pevzner (pzz at apevzner.com)
