    Last night scanimage was working great. This morning I keep getting the scsi_read: snapscan_cmd command failed: Error during device I/O
    scanimage: sane_read: Error during device I/O
    error.
     
    I have tried different settings, etc. Xscanimage locks up upon changing the mode from Colour to anything else. I am guessing that this is something to do with the scanimage problems.

    I have a text file with the output of scanimage in SANE_DEBUG_SNAPSCAN=255 mode, at http://playstation.webhostme.com/other/snapscan_debug_output.txt

    I have had this scanner working great under sane 1.0.1, but 1.0.4 seems to be a bit of a problem. It is an Acer 640U. I am using the CVS snapscan backend which included support for this scanner.

    I noticed that in this version of the snapscan backend that if the scanner outputs FlatbedScanner13 that the PRISA620 is selected. When everything was working before, the older snapscan backend selected SNAPSCAN600 on a FlatbedScanner13. I would have changed this to begin with, but I read in the archives of this list that there were some color alignment problems with the old backend.

    I am not sure if this makes a difference, but the firmware that works for me is called U96V121.BIN. This is different from most people with an acer 6**U* scanner. ie, 620U, 640UT, etc.

    Thanks for the support people.
