Thank you for your prompt reply. I have tried holding onto buttons, every one of them, and none of the values change. I have tried compiling with "scanbuttond =yes" with the same results. When installing the kodak official driver, it does provide a kds_i1000.conf which lists the usb and ID's of various models, just like the other backends in the sane.d folder.
Have I understood incorrectly if the scanner really support sane?

scanbd depends on sane to detect button presses. For rare cases there is
the old scanbuttond backend included into the sources of scanbd. In this
case, you have to manually compile and install scanbd.
In the log-file you will find all options (including the buttons id they
are detected by sane) of the scanner. While looking at the log-output of
scanbd you can identify the button related options if you press a button
for more than say 0,5s. If the button can be monitored by scanbd you
must see a value-change for this specific option. Try all buttons.
If you don't see a value change of any option, than the sane driver is
not supporting this device.
But be aware, that the names of the options are sometimes not obviously
related to their function ...
