This card seems to work with the g_NCR5380 driver (but only with<br>
|
|
the mustek patch supplied in the same directory as SANE itself.<br>
|
|
You have to supply some additional parameters, for using as a module<br>
|
|
'modprobe g_NCR5380 ncr_addr=0x280 ncr_irq=255 dtc_3181e=1' works<br>
|
|
for me. <br>
|
|
<p>
|
|
At first I thought there is some trouble with the driver since my<br>
|
|
scanner (ScanExpress 12000SP) doesn't work with the mustek<br>
|
|
backend. But yours should work.<br>
|
|
<p>
|
|
But now I've made some progress, it seems that the scanner's <br>
|
|
SCSI implementation is *very* crippled, even after totally weird<br>
|
|
commands the scanner never sends any error code at all.<br>
|
|
Only INQUIRY worked first, but according to David's hint I am<br>
|
|
trying SCSI-II commands, and --- what a surprise --- something<br>
|
|
happens. After SET_WINDOW and SCAN the slide moves slightly<br>
|
|
forward, and back to the home position after closing the device.<br>
|
|
<p>
|
|
And READ produces some noise like moving the slide back and forth<br>
|
|
a few scanlines, perhaps continuous backtracking because the<br>
|
|
scanner can't get rid of the data. Unfortunately, the SCSI-II<br>
|
|
standard isn't very precise concerning how to specify the <br>
|
|
amount of data to be transferred. I don't know what the 'blocksize'<br>
|
|
actually is.<br>
