Hi Henning,

as far as I know libusb in no more necessary with linunx-2.6
so I have not installed it. 
I think it would things confuse even more.

I have no probles to go with sane-backends-1.0.12 in the meantime.

If you want test your changes I will do. 
I have made script to simplify build and install,
so a switch between versions is a matter of a few seconds.
