The card is connected to the PC via USB and when I say it "disconnects" I mean as if I physically unplugged the card for a nanosecond. This problem occurs a lot for example on f1 2020 but is almost absent on Assetto Corsa, Grid 2019. At the moment 22 LEDs and a nextion 4.3 are connected to the card but the problem occurs even if nothing is connected at all. I tried to change the USB cable, the PC out port between 2.0 and 3.0 but nothing has changed. Sometimes these disconnections / reconnections are so "violent" that all the other devices that I have connected to the other usb of the pc are also deactivated.
