[sane-devel] scanner buttons, was: Simplified installation procedure for Redhat Fedora Linux 1.0 and Epson 1670 scanner, also a report of a bug?

[m. allan noah]

ok, just to recap what i am seeing here.

1. we would like a backend to be able to signal a frontend when a button 
or sensor is tripped.

2. if the backend is polled, it needs a way to request the polling 
interval.

3. the stati are generally not accessed via a separate command for each 
sensor, but instead, there is one command that gets a bitmask from the 
scanner.

4. we would like as many of these sensors as possible to have well-known 
names so that a front-end could set sane (pun intended) defaults.
