USB device work fine in VISA test panel but VISA read VI in LabVIEW it does not work

Hello, I am trying to connect my Gauge Digital Gratten (or Atten) GA1202CAL to my PC through the usb, but I can not read the oscilloscope response. The oscilloscope (USBTMC class) works well with its original software, but the software is too simple and does not take full advantage of the oscilloscope's capabilities. Therefore, I am doing a VI to control it, but the "VISA read VI" always returns the error: (Hex 0xBFFF0015) The waiting time expired before the operation was completed. The "VISA write VI" works excellently, I can write all the commands and the oscilloscope executes them without problems.
When I use the NI MAX "VISA test panel" it is possible to establish communication without problems, I can write all the commands and read the answer correctly, but it does not happen in LabVIEW.
I have no idea what the problem may be, help is needed.
thanks
