Hi Roy, Hi Oliver,
I got the logfile from Oliver and discovered that the scanner returns unexpected
data with the scsi_read_image_info command. Normally it gives back the width and
height of the image to be scanned and the amount of data it will provide. But here
it looks like the scanner simply returns the bytes it has recieved during the last
command (scsi_set_window).
By the way, have you modified the backend code? I would have expected that you get
an error message because your model (model code 0x99) is not recognized by the
backend.
In fact I think there are two possibilities:
a) Microtek again doesn't follow it's own standards with newer scanners and the
scanner must be handled different from the others
b) there is a problem with the sg / USB driver or interface
to make this clear it would be helpful to know about the communication with the
scanner when scanning with Windows. I got my (SCSI-via-)parport scanner running
with wine and was able to trace the data that was send via the ASPI interface. I
don't know if it is possible with SCSI-via-USB.
Greetings
Karsten
