[sane-devel] ScanJet 4c, scanimage hangs

[Nathan Cassano]

Hi folks,
	I'm working on installing a hp scanjet 4c scanner, attached to a
Symbios Logic 53c416 SCSI card on a Suse Linux 2.2.16 box. Everything
relating to the kernel appears to be setup correctly (isapnp, modules,
scsi). The scanner is set to the ID of 1, is the only device attached
and is terminated. My problem is whenever I execute "scanimage" the
systems creeps . The operation executes succeeds but it takes ~20
minutes.

So I set SANE_DEBUG_HP to 255 and ran "scanimage -L". The following is
the program output.

# scanimage -L

This goes on for a very long time doing a bunch of testing.
And finally ends with.

My dll.conf reads

My hp.conf reads

Does anyone know whats going on?
