Hi Henning,

Some months after I have time to try agian to configure SANE to work 
with my Acer ScanPrisa 640 U Scanner. Now I have Mandrake 9.0 and sane 1.0.9

'scanimage -L' gives me the following:

device 'snapscan:/dev/usb/scanner0' is a Acer FlatbedScanner16 flat bed 
scanner

I found on Internet that file u64v119.bin is the firmware for this 
scanner, so I changed snapscan.conf file entering the address and name 
of this file (/mnt/win_c/windows/usbbin/u64v119.bin).

However wen I run scanimage -d snapscan:/dev/usb/scanner0  the scanner 
start to make some noise and I got the following:

scanimage: sane_start: Error during device I/O

Also I made a directory /home/myname/driverscanner.bin/ and placed here 
the firmware file and changed again the address in snapscan.conf file. 
By the way I made 'chmod 777 snapscan.conf' and 'chmod 777 u64v119.bin' 
in both addresses, but the answer is the same.
