IIRC, there haven't been found any timing issues in saned in recent
years. Using saned changes the timing (and may change buffer sizes
etc.). This may reveal problems in the backend or the scanner itsself.
I don't say that saned is perfectly free of bugs but it's long time
ago that really a saned bug caused a backend to stop working.

Also in that case I think no bug in saned was found.

No firewall/packet filter involved? From your first log it really
looks like something blocks the data port.

If that's not the case, please also check the recent thread about the
Umax Astra 2200 network problems and send debug logs as mentioned
there. Please try to reproduce the hang when debugging is enabled.
