OK, I've found out where the backend hangs. It enters an infinite
|
|
<BR>
|
|
loop in "measure_transfer_rate". When tested with res=100, x=55, it
|
|
<BR>
|
|
tries to read 31104 bytes (in 48 lines of 648 bytes), but only ever
|
|
<BR>
|
|
gets 29808 bytes.
|
|
<BR>
|
|
<P>It loops forever waiting to get the last 1296 bytes (two lines), which
|
|
<BR>
|
|
never arrive.
|
|
<BR>
|
|
<P>The 31104 that it expects comes from "pss->read_bytes", which (I
|
|
<BR>
|
|
guess) should be filled with the actual number of bytes available by
|
|
<BR>
|
|
the earlier call to "scsi_read (pss, READ_TRANSTIME)".
|
|
<BR>
|
|
<P>Anyway, changing to line
|
|
<BR>
|
|
<P> if (status != SANE_STATUS_GOOD)
|
|
<BR>
|
|
<P>to
|
|
<BR>
|
|
<P> if (status != SANE_STATUS_GOOD || ndata == 0)
|
|
<BR>
|
|
<P>fixed the problem. I suspect there should be a cleaner fix, since I
|
|
<BR>
|
|
don't really know what I am doing.
