Hi all,<br>
|
|
My problem with the calibration is simple: I can't get it to perform the<br>
|
|
calibration. I'm using sane 1.00 with the build-1 patch for the umax drivers<br>
|
|
and xsane 0.18 for the frontend (tried xscanimage too).<br>
|
|
I stuck a debug message in the code to supplement the messages already<br>
|
|
there and found that dev->do_calibration was zero when the scan process went<br>
|
|
through the do_calibration() function even when the box for "Quality<br>
|
|
Calibration" was checked in the interface. The code checks and to me seems<br>
|
|
to only perform the calibration if this is nonzero. I don't know if this is<br>
|
|
a problem in the driver itself or somewhere else but both xsane and<br>
|
|
xscanimage exhibit the same problem. That's as far as I got, I have final<br>
|
|
exams for the next two days (take homes) so I won't be able to fiddle again<br>
|
|
until after that probably, but I figured I'd say something so someone with<br>
|
|
better knowledge of the code can maybe investigate.<br>
|
|
<p>
|
|
oh, btw, /proc/scsi/scsi says<br>
|
|
Host: scsi0 Channel: 00 Id: 05 Lun: 00<br>
|
|
Vendor: UMAX Model: Astra 1220S Rev: V1.1<br>
|
|
Type: Scanner ANSI SCSI revision: 02<br>
|
|
<p>
|
|
<p>
|
|
Which I presume means it's firmware 1.1, (out of a possible 1.5, ugh).<br>
|
|
<p>
|
|
Thanks,<br>
|
