TIPS and TRICKS

ppdev0: no associated port!

        If you see messages like 'ppdev0: no associated port!' in system log (check with the dmesg command), it's because your system didn't load low level parallel port driver. On PC, add a line 'alias parport_lowlevel parport_pc' in /etc/modules.conf to have it loaded when needed. Depending on your machine architecture, you can use parport_amiga, parport_cs, parport_pc, parport_arc, parport_gsc, parport_serial, parport_atari, parport_mfc3, parport_sunbpp.

  • unplug parallel port cable from the PC (3)
  • plug in scanner's power supply (1)
