etoken unaccessible after reading

I´m trying to read out the certificate of an etoken. I´ve followed the answer from Keystore from digital signature e-token using java. It´s giving me the certificates installed in the token but after that the token isn´t reachable anymore. Did somebody got something similar while accessing a token?

// Create instance of SunPKCS11 provider 
String pkcs11Config = "name=eToken\nlibrary=C:\\path\\to\\your\\pkcs11.dll"; 
java.io.ByteArrayInputStream pkcs11ConfigStream = new java.io.ByteArrayInputStream(pkcs11Config.getBytes()); 
sun.security.pkcs11.SunPKCS11 providerPKCS11 = new sun.security.pkcs11.SunPKCS11(pkcs11ConfigStream); 
java.security.Security.addProvider(providerPKCS11);  // Get provider KeyStore and login with PIN String pin = "11111111"; 
java.security.KeyStore keyStore = java.security.KeyStore.getInstance("PKCS11", providerPKCS11); 
keyStore.load(null, pin.toCharArray());  // Enumerate items (certificates and private keys) in the KeyStore 
java.util.Enumeration<String> aliases = keyStore.aliases(); 
while (aliases.hasMoreElements()) {
    String alias = aliases.nextElement();
    System.out.println(alias); 
}

The problem persists, after plugging out/in the token is reachable again, but after running the code, the token seems to be locked again. OS Win2k8 Server.

Finally got this clear. After disconnecting other USB devices the Token responds as usual.

The Token should be plugged in to a fully powered port. Best on a separate Host- Bus.
