[sane-devel] Version of net-snmp

In my backend for kodak aio printer scanning  here
I've now got a working auto detection system using functions from cups.
If you have an aio you are likely to have cups installed, and most distros 
would install cups.
Whereas Ubuntu for example has net-snmp 5.4.3 and not 5.6

This backend now works very nicely with network connection of the aio.
But not so well with USB, since I have some problems with the bulk transfer
