    You seem to be more lucly than me, here's my dmesg with the same
    procedure:
     parport0: PC-style at 0x378 [SPP]
     parport1: PC-style at 0x278 [SPP,PS2,EPP]
     parport0: no IEEE-1284 device present.
     parport1: no IEEE-1284 device present.

    my scanner is on parport1

    Here, you must try: > insmod ppscsi

    your dmesg will be full of epst traces:

     scsi : 0 hosts.

    In my case, the parallel port returns the same values on the
    two physical parallel port, even if there is device plug on it.

    If you've done some other experience with your scanner...
