What does:
  ls -l /sys/bus/usb/devices/

print?


It works on my box:
  [kay@pim ~]$ udevinfo -a -p/sys/class/usb/lp0

  device '/sys/class/usb/lp0' has major:minor 180:0
    looking at class device '/sys/class/usb/lp0':
      SYSFS{dev}="180:0"

  follow the class device's "device"
    looking at the device chain at '/sys/devices/pci0000:00/0000:00:1d.1/usb3/3-1/3-1.3/3-1.3:1.0':
      BUS="usb"
      ID="3-1.3:1.0"
      SYSFS{bAlternateSetting}=" 0"
      SYSFS{bInterfaceClass}="07"
      SYSFS{bInterfaceNumber}="00"
