[fprint] Problem with udev-rules on 147e:2016

Hi All,
I use Arch Linux x86_64 on Thinkpad T510.Kernel version 3.1.1, udev 175.
During boot, after "Waiting for UDev uevents to be processes" I
see:udevd[246]: error opening
ATTR{/sys/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.3/1-1.3:1.0/power/control}
for writing: No such file or directoryudevd[246]: error opening
ATTR{/sys/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.3/1-1.3:1.0/power/control}
for writing: No such file or directory
However, fingerprint sensor seems to work. I found the reason for the
error messages, it's
/lib/udev/rules.d/60-fprint-autosuspend.rules:SUBSYSTEM=="usb",
ATTRS{idVendor}=="147e", ATTRS{idProduct}=="2016", ATTRS{dev}=="*",
ATTR{power/control}="auto"...SUBSYSTEM=="usb",
ATTRS{idVendor}=="147e", ATTRS{idProduct}=="2016", ATTRS{dev}=="*",
ATTR{power/control}="auto"...
These rules contain my device 147e:2016 two times (why?), so I get two
error strings.
$ ls -1 /sys/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.3/1-1.3:1.0/powerasyncruntime_active_kidsruntime_enabledruntime_statusruntime_usage
How I should change rules? Any suggestion is appreciated.
