Hello, I went into a potentially related problem with a USB scanner. It is working fine in Lucid but fails in Oniric. After some investigation I narrowed down the problem to the mtp-probe script which is run by udev rules when USB devices get connected. As fas as I understand this is supposed to check if a generic USB device has MTP capabilities. See my question here [1] for more details.
In order to verify if your smartcard reader is also "mtp-probe" unfriendly you could try to temporary rename /lib/udev/mtp-probe. For my scanner this was enough to bring it back. See [1] for a more persistent solution. I noticed other udev rules "exceptions" for some "sensitive" devices in upstream code used by libmtp people to build udev rules: shall we add exceptions for any buggy device which does not survive a mtp-probe? I have no idea where is the best place to fix this... Please, let me know if this is really related to my problem.
