Henning, currently there is no way to change the timeout value programatically. (one more issue that should be fixed in Sane 2) I think that increasing the default timeout value is not a problem, unless we return to the _really_ long value of 10 minutes, as we had it before. It's simply too boring to wait for 10 minutes until you get an error ;) Perhaps we could use an enviroment variable to increase or decrease the timeout -- just in case that we have again a too short timeout value for some scanners...
