Yes, I have now tested Epson Perfection 1640SU with the TPU (film 
adapter) option (replaced the ADF) using xsane and this works!
The TPU/Flatbed sources became available in xsane. I scanned a slide in 
the TPU, used Positive Film with 14 bit Color depth (the scanner's 42 
bit not supported) and resolution 3200.

In addition, I've noted the following documents about this scanner:

http://www.freecolormanagement.com/sane/faq.html

"The timeout value still has to be increased. The time the scanner needs 
to complete some operations depends on the resolution and the bit depth. 
For the newer 1600dpi models it seems to be necessary to increase the 
timeout to 80 seconds".

Could it be worth to try to increase the timeout (for the ADF); and if 
possible how is the commands to do it?
