Eduardo,<br>
|
||
<p>
|
||
Sounds to me like that there is a small buffer in the device driver<br>
|
||
(scsi/pp/etc) or the reading process (SANE backend) is requesting little<br>
|
||
chunks of data. Irregardless, you *should* end up with an image...hmmm,<br>
|
||
you might have another issue.<br>
|
||
<p>
|
||
I've experienced much of the same issues while writing my USB device<br>
|
||
driver and trying to find an optimal read buffer.<br>
|
||
<p>
|
||
