[sane-devel] Acer Prisa 620ST

[ken at scrye.com]

Hi,
  I'm attempting to use sane-1.0.3-10.1 with an Acer Prisa 620ST.  An
  older version of sane worked mostly fine, but the latest version
  will not scan in color.  The debug output shows: 

[snapscan] sane_snapscan_start: after measuring speed:
        1911 bytes per scan line
        11.100000 milliseconds per scan line.
        ==>172.162156 bytes per millisecond
[snapscan] reserve_unit
[snapscan] snapscan_cmd
[snapscan] calibrate: reading calibration data
[snapscan] read_calibration_data
[snapscan] snapscan_cmd
[snapscan] read_calibration_data: read 244352 of 244800 calibration data
[snapscan] calibrate: read_calibration_data command failed: Error during device I/O
[snapscan] sane_snapscan_start: calibration failed.
[snapscan] release_unit
[snapscan] snapscan_cmd
[snapscan] sane_snapscan_cancel
[snapscan] release_unit
[snapscan] snapscan_cmd
[snapscan] close_scanner



Grayscale scanning works just fine.

Thanks,
