In reply to both Marc and Roland, I confirm and say:

1. usbd is really running all the time (usbd_enable="YES" being in rc.conf)
2. using the default usbd.conf, which I studied only recently to find out what could be missing.
3. added the following lines to it for testing:
device "Perfection 1650 scanner"
        devname "uscanner[0-9]+"
        attach "sane-find-scanner -q"
        detach "sane-find-scanner -q"

I still haven't got a clue of what other command could be useful here. I think Ialso understood that the proper attachment/detachment function of usbd has nothing to do with those commands. Right or wrong?
4. Killing usbd and running ``usbd -dvv'' confirms that usbd does not detect any event when I connect or disconnect the signal cable of the scanner (needless to say that the scanner is connected to power). No error message in the debugging output, just this:

algol{me} ~ # usbd -dvv
usbd: opened /dev/usb0
usbd: reading configuration file /etc/usbd.conf
usbd: action 1: ActiveWire board, firmware download
.
.
.
usbd: action 6: Perfection 1650 scanner
  devname: uscanner[0-9]+
  attach='sane-find-scanner -q'
  detach='sane-find-scanner -q'
usbd: action 7: USB device
usbd: 7 actions
usbd: opened /dev/usb
usbd: doing timeout discovery on /dev/usb0
usbd: processing event queue due to timeout on /dev/usb
etc, etc ad infinitum

No event, no action. Normal.
