Hi, Damcha.  I'm glad you got it working, but I would be a little concerned
about just removing these calls altogether as opposed to trying to find out
if there's a proper replacement in the newer kernels.

This OID isn't supported on the PSC500.  I don't remember if this is the
right error or if it's failing for some other reason.  Try some of the
others, like OID_DEV_MODEL_NAME.

Please try downloading version 0.6.  It contains a patch to SANE 1.0.3 to
allow scanning on some of the OfficeJets (including the PSC500).

If you're willing and able to do some kernel-level hacking like this, I
would certainly appreciate it.  I'm familiar with the communication
protocols but rather ignorant when it comes to kernel issues.  :-)

It also seems that the kernel-mode drivers are broken for SMP.  I'll forward
the e-mails I've been exchanging about that, in hopes that you or somebody
else might be able to figure it out.
