libieee1284 and canon parallel scanners

Hi,
I'm desperately trying to get my parallel port scanner to work on
FreeBSD 5-STABLE.
It is a canon 640P scanner, that in theory should work with sane-backends
and canon_pp driver (which depends on libieee1284).
Instead, it can't detect the scanner. I posted to sane-devel to try
to get some feedback, however there may be some FreeBSD-specific
issues (see
http://lists.alioth.debian.org/pipermail/sane-devel/2005-April/013400.html ).
(please see the link for details).
In summary:
dmesg under FreeBSD shows:
ppc0: <Parallel port> at port 0x378-0x37f irq 7 on isa0
ppc0: Generic chipset (ECP/PS2/NIBBLE) in COMPATIBLE mode
ppc0: FIFO with 16/16/8 bytes threshold
ppbus0: <Parallel port bus> on ppc0
lpt0: <Printer> on ppbus0
lpt0: Interrupt-driven port
ppi0: <Parallel I/O> on ppbus0
libieee1284 is installed, if you run the test utility you get:
Found 3 ports:
0x278:
0x378:
0x3bc:
0x278: 0x278
RAW NIBBLE BYTE COMPAT ECPSWE
0x378: 0x378
RAW NIBBLE BYTE COMPAT ECPSWE
0x3bc: 0x3bc
RAW NIBBLE BYTE COMPAT ECPSWE
But the scanner is not detected!
Sorry if this post is a little off-topic, I'm looking for parallel
port gurus who might
be able to help. e.g. do I need some random SCSI driver or something.
Cheers,
Rob Pollock.
