My Raspberry Pi 4 model B both USB 2.0 and 3.0 ports have not working since very long,
I just got to know about testing points in Pi but I don't know which ones to test for the USB ports. I plug them in with the raspberry pi dedicated adapter but they wont show any signs of power to my USB mouse and flash drives are also not detected. What are the power test points and expected voltages for the USB ports ?
I tried every other things I hope to get a better insight from the testing points
