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

[microtek2] scsi_send_gamma: pos=0x805a5b8, size=3072, word=0, color=3
[microtek2] scsi_wait_for_image: ms=0x8055820
[microtek2] scsi_read_image_status: ms=0x8055820
[microtek2] scsi_read_image_status: 'Error during device I/O'
[microtek2] scsi_wait_for_image: 'Error during device I/O'
[microtek2] cleanup_scanner: ms=0x8055820
scanimage: sane_start: Error during device I/O

but there are other problems that I think need to be resolved. Further
development is currently on hold until some issues get worked out.

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