<EM>&gt; &gt; I am having problems using my HP ScanJet 4c. When I try to scan, I
</EM><BR>
<EM>&gt; &gt; receive the message &quot;Error during divice I/O&quot;.
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; What are some possible solutions? I have tried recompiling the kernel
</EM><BR>
<EM>&gt; &gt; (2.4.1) with different SCSI options.

<EM>&gt; Jody,
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; This might be related to a too short timeout in the part of Sane's SCSI
</EM><BR>
<EM>&gt; library for the new Linux SG driver in the 2.4 kernel.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Please try to change the following line in sanei/sanei_scsi.c
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; req-&gt;sgdata.sg3.hdr.timeout = 10000;
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; (line 1892 in Sane 1.0.4) to:
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; req-&gt;sgdata.sg3.hdr.timeout = 1000 * 10 * 60;
