    Atom no connection to the PCs

    I have a problem with LINK G4+ Atom. There have no connection to the PCs but the ECU is working. The error is "Unable to connect to the ECU but USB connection is present. Please cycle the power to the ECU.". The COMPORT is available on PC "device manager" and in "PCLink G4+" application. I opened the case of device(ECU) and see the USB to UART converter is CP2102. The transmit pin is 26. I see the communication with oscilloscope. But on Pin 25 (receive RX PIN) have only static logical level, no response from main ECU controller.
