It's interesting that the same message about not claiming the interface
appears in the log when I print something, but it prints fine.

I believe it installed correctly.

The version I had was 1.6.9. I have installed 1.6.10 just now.

So now I have 1.6.10 installed. It appeared to install without any
problems. 1.6.9 is all gone too. But the scanning problems remain.

My platform is slightly exotic but fairly inexpensive. I am running on a
powerpc-based kurobox.
My distribution is gentoo. I'm betting you probably cannot help me with
gentoo (it's a great platform though). Anyway, I had to create my own
ebuild for 1.6.10 because an official one is not yet available, being so
new. With gentoo, an "ebuild" tells the system how to download the source,
build and install. It's a lot like installing from source.
I don't know if you will really be able to reproduce my problem in-house ...
it's nice of you to offer though. Have I given you enough details about my
system?
I am open to suggestions. I can always resort to using usbmon and compare
against my AMD64 gentoo box which scans successfully (but I want the kurobox
to be the scanner server since it makes a great print server).
Thanks and regards,
