Openpcd reader not working

[Chopra, Kirti]

 Hi,
  I am using Ubuntu 8.04  and openpcd RFID reader v04. I have been able to compile librfid and build firmware. I can also set red LED on and off. Now that I am trying to read an ISO 14443 B credit card or a ISO 15693 tag , the reader does not detect the card. The message I get is

initializing librfid
opening reader handle OpenPCD, CM5x21
scanning for RFID token...

also sometimes it does not detect the reader at all. The message I get is

initializing librfid
opening reader handle OpenPCD, CM5x21
No OpenPCD found
No Omnikey Cardman 5x21 found

Can anyone please tell me what is the possible problem?

Thanks & regards
Kirti
