You can try different USB ports. When I plugged it in USB 3.0 ports, the problem magically disappeared.
I tried but same issue i think there’s a fault in dc dc converter lxdc55k
Do you have a voltmeter? Would suggest to measure voltage outputs of DC-DC converters.
yes i have fluke multimeter and i will measure the outputs of dc-dc converters
