[CentOS] Scanner missing again

A while back I posted about my new HP J3600 scan/fax/copy/print-er and how
it was visible to the root but not me as an ordinary user. I had no trouble
configuring it as a printer, but the scanner was invisible to xsane until I
added my user id to the lp group.
Now it's gone again, except that it is visible as a usb device to me as a
normal user, but xsane can't seem to find it any more.
Since this was working on the 2.6.18-194.11.4 kernel, I rebooted that one,
but it exhibited the same behavior, so I wrote off the new (...17.1) kernel
as innocent. However, I am getting an error during startup on hpssd - it
complains about python-dbus being missing. I can't find that either, but
there _is_ a dbus-python 0.70 installed and it wants a version > 0.80, so I
hauled down 0.83, built it and installed it and that didn't seem to help.
I will try that when I have a few minutes to take the system down again, but
in the mean time, can anyone hazard a guess at what's wrong?

It's Bus 2, Dev 6. There is nothing in any of the /var/log/* files to
indicate any kind of problem for yesterday, when the problem appeared, other
than my fumbled three attempts to input the password for 'sudo xsane'.
What's interesting is this:
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.
# No SCSI scanners found. If you expected something different, make sure
# you have loaded a kernel SCSI driver for your SCSI adapter.

So, sane-find-scanner finds the scanner, but xsane does not??? (For the
record, on the 11.4 kernel, sane-find-scanner could _not_ find the scanner,
but that was before I installed the newer dbus-python.)
This was working perfectly a few days ago. I'm not sure where else to
