Thanks Henning, I guess I should have been clearer.

Yes, umax_pp is enabled in dll.conf. I have tried all three suggested 
ports in umax_pp.conf with mixed results.

Port 0x278 yieds the following:
[sanei_debug] Setting debug level of umax_pp to 255.
[umax_pp] init: SANE_Auth_Callback not supported (yet) ...

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
[umax_pp] exit: (...)

Port 0x378 resets my printer (it is on a feed-through attached to the 
scanner) and prints the following:

According to the commentary and the man pages, I should be configuring 
the driver to use 0x3c8 since it is attached to /dev/lp0. This doesn't 
seem right since the old driver always found the scanner on 0x278.

Thanks for any additional help.
