    I open this topic due to the fact that I had a problem with the IC 7300 when connecting to the USB port.
    Probably due to poor grounding, the input to the USB port has failed. We found three defective components: R621, R622 and EP601.
    After the replacement, everything returned to normal.

    I am making this post in the hope that it may be useful to an IC 7300 owner who is in no way able to connect the USB port to a computer.
    For more information you may email me: danyseb_msm@yahoo.co.uk
