Could you set the debug a bit higher for me (say, 200)?

Unfortunately the ppc interface doesn't do what libieee1284 needs, so it resorts to direct io port access (via /dev/io). That's why you're seeing the three ports. I lied above.. you can use it as non-root by modifying the permissions on that file. > libieee1284 is installed, if you run the test utility you get: > > Found 3 ports: > 0x278: > 0x378: > 0x3bc: ... > Anyway, I am really quite keen to get this working, anyone able to help out?? Try specifying the port that you know you have (0x378) in your canon_pp.conf file, that makes the driver default to trying that port first. Otherwise, I'm not sure what might be wrong. The libieee1284 FreeBSD support was written a while back and I've never been very happy with it. I think it requires the time of a more knowledgable FreeBSD person than myself. > Thanks heaps, > > Rob Pollock. Cheers, - Matthew Duggan
