Yes, you are right.  As long as the transparency unit is disconnected 
before the scanner is plugged in, xsane's preview will work.  After you 
mentioned the transparency unit, I found Till Kamppeter's posting on 
this issue from October of last year and read the thread.  I can confirm 
that the device address may change after the firmware is uploaded, but 
even when the address does not change, preview still does not work, nor 
does restarting xsane help.  I can also confirm that esfw41.bin is the 
correct firmware.  This is what is installed under Windows.  I also see 
the delays:

[snapscan] Scanner warming up - waiting 9 seconds.
[snapscan] Scanner warming up - waiting 33 seconds.

I had actually assumed that these were necessary-- that the scanner 
really did need time to warm up.  But I should try to do a scan with the 
old Windows machine and see if any similar messages are displayed.
