I don't know what the permissions are, but all this was being done as<br>
|
|||
|
|
root. I think we've progressed beyond this point, though. The error<br>
|
|||
|
|
sequence is now:<br>
|
|||
|
|
<p>
|
|||
|

[microtek2] scsi_send_gamma: pos=0x805a5b8, size=3072, word=0, color=3<br>

|
|||
|
|
[microtek2] scsi_read_image_status: ms=0x8055820<br>
|

[microtek2] scsi_read_image_status: 'Error during device I/O'<br>
|

|
[microtek2] scsi_wait_for_image: 'Error during device I/O'<br>
|

|

|
|
scanimage: sane_start: Error during device I/O<br>
|
|||
|
|
<p>
|
|||
|
|
but there are other problems that I think need to be resolved. Further<br>
|
|||
|
|
development is currently on hold until some issues get worked out.<br>

No, but I don't know if it's a problem with your driver. Right now I<br>
|
|||
|
|
don't think it is. Once more progress has been made, I'll be sure to let<br>
|
|||
|
|
you know if you wish.<br>
