Title:
  After plugging an HP LaserJet 1020 UDEV needs several minutes to set
  up newly connected USB printer

Bug description:
  I have several USB printers (all HP) which I can connect to my Oneiric
  laptop via USB hubs. Everything works well with these printers as long
  as I do not connect the HP LaserJet 1020 (cheapo model which needs to
  get fed with its firmware everytime when it is turned on).

  After booting and before connecting the LaserJet 1020 all works
  correctly. UDEV sets the ownerships and permissions for the
  /dev/bus/usb/*/* file (664, root.lp, plus ACLs) and runs /lib/udev
  /udev-configure-printer to create a print queue if needed and to
  enable the print queue if it is already there.

  As soon as i connect the LaserJet 1020, for everyprinter connected
  afterwards the following happens: In /dev/bus/usb/*/* appears a new
  file with 600 root.root permissions and without ACLs, probably a raw,
  not UDEV-treated entry.  By bus and device number and "lsusb" one can
  see that the entry is actually for the newly connected printer. Only
  after some minutes UDEV does its job of setting the permissions,
  ownerships, ACLs,  and starting /lib/udev/udev-configure-printer.

  I tried with kernel 3.0.0-16 (the current) and afterwards 3.0.0-15.
  syslog is attached.
