It seems I was wrong about the device. Bus 002 Device 003 is actually 
2-2.

Bus 002 Device 002: ID 05e3:0723 Genesys Logic, Inc. GL827L SD/MMC/MS 
Flash Card Reader


I realize now that this device doesn't actually work.

I don't remember whether it ever worked before in Linux.

Which would have been an installation of Kubuntu 14.10.

Anyway, output of some commands in case it still matters:

# udevadm info -a --name=bus/usb/002/002

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
