However, it seems that your scanner needs more time for calibration now.
Patch1 doubles wait time.

If this won't help, we need to accept a new ready flag (command 'da20'
normally is waiting for 0x01 in byte 8 of the response; now we also try
to accept 0x02). For this I prepared patch2.

If both patches won't help, you can reopen bug #314787. It's much easier
to exchange log files via the bug tracker.
