What's the error you got?

When the javacard run on the reader omikey with contactless interface and the reader sends the command 00a4040000, the javacard does not return anything and the reader waits the response time over.

Do you have Bus Hound on your PC? I think you may post the data obtained from Bus Hound.

I use the bus hound to view the data flow and I found no data sended by the card when the card received the command:00a4040000.

e... Is your PC OK? Or is your omikey reader OK? I think add a hub between pc and reader may help you to resolve the question.

The other PC can run the javacard ok and my PC run it err.
The Omikey reader should be ok.
I will use the hub to test this question.
thank you very much!
