usb printer problem

["Thomas H. George" <georgeacct@spininternet.com>]

I successfully built a 2.2.19 kernel with usb support.  cat 
/proc/bus/usb/drivers shows drivers loaded, cat /proc/bus/usb/devices 
shows only pci.  I have

none    /proc/bus/usb    usbdevfs    defaults    0    0

in fstab.  After booting up dmesg reports

  parport_probe: failed
  parport0: no IEEE-1284 device present

and then later in the listing

  lp0: using parport0 (polling)

Therefore when I try to print lpq reports lp0: no such device.

I could rebuild the kernel with no parport support (only a Visioneer One 
Touch 7600 scanner is attached to the parallel port and I don't believe 
there is any way to use this with linux) but sometime I might have 
something usable on the parallel port and still want to use the usb printer.

Is there something I have omitted which prevents lp0 from being assigned 
to the usb port?
