Whoo Hoo!
<BR>
<P>After modifying hp.conf and doing a 'chmod 666' on /dev/sga (/dev/sg1
<BR>
was a symlink to sga) everything now works! yay. I think I'm gonna write
<BR>
a nice howto for this... it's was rather painful.

<EM>&gt; &gt; &gt; &gt; I need to find a howto or at least some help in getting sane to find my
</EM><BR>
<EM>&gt; &gt; &gt; &gt; parallel port scanner. All the ppSCSI modules are loaded, the HP 5200C
</EM><BR>
<EM>&gt; &gt; &gt; &gt; is supported... but sane can't seem to find any device with a scanner
</EM><BR>
<EM>&gt; &gt; &gt; &gt; attached.
</EM><BR>
<EM>&gt; &gt; &gt;
</EM><BR>
<EM>&gt; &gt; &gt; What does 'cat /proc/scsi/scsi' say. Can you see your scanner
</EM><BR>
<EM>&gt; &gt; &gt; listed there? Is the sg driver built into the kernel or loaded
</EM><BR>
<EM>&gt; &gt; &gt; as a module? [To list loaded modules used 'lsmod'.]
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; under /proc/scsi I find epst and scsi cat'ing scsi I get:
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; Attached devices:
</EM><BR>
<EM>&gt; &gt; Host: scsi0 Channel: 00 Id: 00 Lun: 00
</EM><BR>
<EM>&gt; &gt; Vendor: HP Model: C7190A Rev: 3846
</EM><BR>
<EM>&gt; &gt; Type: Processor ANSI SCSI revision: 02
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; cat'ing epst/0 I get:
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; ident: epst 0.92 (0.92), Shuttle EPST
</EM><BR>
<EM>&gt; &gt; base port: 0x378
</EM><BR>
<EM>&gt; &gt; mode: 0
</EM><BR>
<EM>&gt; &gt; mode name: Nybble
</EM><BR>
<EM>&gt; &gt; delay: 1
</EM><BR>
<EM>&gt; &gt; nice: 0
</EM><BR>
<EM>&gt; &gt; verbose: 0
</EM><BR>
<EM>&gt; &gt; quiet: 0
</EM><BR>
<EM>&gt; &gt; tot_cmds: 31
</EM><BR>
<EM>&gt; &gt; tot_bytes: 584
</EM><BR>
<EM>&gt; &gt; tot_errs: 0
</EM><BR>
<EM>&gt; &gt; parport device: parport0
</EM><BR>
<EM>&gt; &gt; claimed: 0
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; The above looks good.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; &gt; I think that hp.conf may be screwed up it currently says:
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; /dev/scanner
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; /dev/scsi0
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; The /dev/scsi0 looks incorrect (for Linux). Remove it, then
</EM><BR>
<EM>&gt; see if 'ls -l /dev/scanner' is active; in your case it
</EM><BR>
<EM>&gt; should be a symbolic link to /dev/sg0 (or to /dev/sga depending
</EM><BR>
<EM>&gt; on your distribution). Hopefully, the HP backend recognizes the
</EM><BR>
<EM>&gt; C7190A model.
</EM><BR>
