[sane-devel] multi-pass microtek

[Markus Bertheau]

Hello,

I have a Highscreen Realscan scanner that is supported by the microtek
backend. Single pass scans work fine, but multipass scans don't. the
first pass is ok, then the scanner moves the tray(?) back. There the 
following happens:

[microtek] .mode_select_1 3...
[microtek] .wait_ready 3...
[microtek] .start_scan...
[microtek] SENSE!  fd = 3
[microtek] sense = 60 10 06 08.
[microtek] end_scan...
[microtek] .stop_scan...
[microtek] SENSE!  fd = 3
[microtek] sense = 60 10 06 08.
//                 ^^
[microtek] end_scan:  OY! on stop_scan
scanimage: sane_start: Device busy
[microtek] sane_cancel...
[microtek] end_scan...
[microtek] sane_close...
[microtek] sane_exit...
[microtek] sane_exit:  MICROTEK says goodbye.

the marked sense[0] code was not handled in the appropriate fn in
microtek.c. I changed it to return SANE_DEVICE_BUSY (or so). That's the
result. Maybe the problem lies in wait_ready, that doesn't really wait
for the scanner to return it's tray?

Any ideas?

TIA
