The ACR122/Touchatag/Tikitag RFID reader do not seem to be working on BT4. I have yet to discover if the PCSC-Lite drivers have been installed for RFID readers. If not, then I don't think we will be able to use any of the ACS RFID tools. I have the reader working on my OpenSuSe box, but its not running with BT4. Anyone else have this problem?
