My raspberry pi USB can’t use after I download LCD show.
Hello, would you please elaborate a little more? Which version of the Raspberry pi are you using? And what code/library did you download? Is the Raspberry pi not booting at all? Or there had been only some problems with the USB port?
This is the point where I typically reflash the SD card, It takes a bit of time but it validates the the base pi is still working.
I have reflash the SD card,and it is working now.Thank you very much.
