Omnikey 5421 can't read SLE4442

I have contact SLE4442 smart card (2W) and Omnikey 5421 smart card reader. My problem is with connection to card. WinSCard's method SCardConnect returns error SCARD_W_UNRESPONSIVE_CARD 0x80100066. What is interesting this problem not exist with Omnikey 5321 (predecessor 5421). I post code that I used to test read of data (Delphi):

function GetResponseFromCard(const FCardHandle: Integer; const APdu: 

string): string;
var
  RetVar : cardinal;
  SBuf   : string;
  SLen   : cardinal;
  RBuf   : string;
  RLen   : cardinal;
  Ppci   : Pointer;
begin
  SBuf := APdu;
  RBuf := StringOfChar(#0,260);
  Ppci := @SCARD_PCI_T0;
  SLen := Length(APdu);
  RLen := Length(RBuf);
  RetVar := SCardTransmit(FCardHandle, Ppci, Pointer(SBuf), SLen, nil, Pointer(RBuf), @RLen);
  if RetVar = SCARD_S_SUCCESS then begin
    Result := Copy(RBuf,1,RLen);
  end else begin
    Result := IntToHex(RetVar, 8);
  end;
end;

procedure TestSLE4442;
var
  FContext: Cardinal;
  PContext: Pointer;
  Res: LongInt;
  ReaderListStr: string;
  ReaderListSize: integer;
  v: array[0..10] of string;
  SelectedReader: PChar;
  phCard: Integer;
  pdwActiveProtocol: Integer;
  ReadedData: string;
begin
  FContext := 0;
  PContext := @FContext;

  Res := SCardEstablishContext(SCARD_SCOPE_USER, nil, nil, PContext);
  if Res = SCARD_S_SUCCESS then begin
    Res := SCardListReaders(FContext, nil, nil, ReaderListSize);
    if Res = SCARD_S_SUCCESS then begin
      SetLength(ReaderListStr, ReaderListSize);
      Res := SCardListReaders(FContext, nil, Pointer(ReaderListStr), ReaderListSize);
      SortOutSubstrings(ReaderListStr,v,[#0]);
      SelectedReader := PChar(v[0]);
      ShowMessage('SelectedReader: '+ SelectedReader);
      if Res = SCARD_S_SUCCESS then begin
        Res := SCardConnect(FContext, SelectedReader, SCARD_SHARE_EXCLUSIVE, SCARD_PROTOCOL_T0, phCard, @pdwActiveProtocol);
        if Res = SCARD_S_SUCCESS then begin
          ReadedData := GetResponseFromCard(phCard, TStringHelper.Hex2Bin('FFB0000000'));
          ShowMessage('Data: '+ ReadedData);
        end;
      end;
    end;
    SCardReleaseContext(FContext);
  end;
end;

Have someone met with this problem? I also asked HID but without answer for now.

Thanks for help. I heard and I tired Synchronous Omnikey API. Vendor answered me that 2WBP is not supported in new 5421. Maybe there is chance using SCARD_SHARE_DIRECT because using this I'm able to connect to SLE4442 using 5421. But this is hard to tell what I can do more without vendor support.
