Hi Frank,

I've tried this. The result is:

[fujitsu] Window set
[fujitsu] 000: 00 00 01 2c 01 2c 00 00 00 00 00 00 00 00 00 00
[fujitsu] 016: 03 b0 00 00 05 89 00 00 00 02 08 00 00 00 00 00
[fujitsu] 032: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 a0
[fujitsu] 048: 20 00 00 00 00 84 00 00 00 00 00 00 00 00 00 00
[fujitsu] Sense
[fujitsu] 000: f0 00 45 00 00 00 00 0a 00 00 00 00 26 00 00 80
[fujitsu] 016: 00 21
[fujitsu]       5/38/0: Invalid field in parm list
[fujitsu] sanei_scsi_cmd: returning 0x00000004
[fujitsu] sane_start: ERROR: failed to set window

What is the meaning of the these bytes?
