problem with touch screen of the DFR0524 display
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
I purchased the DFR0524 display a week ago. I have scrupulously followed the instructions given here: https://wiki.dfrobot.com/5.5__HDMI_OLED ... KU_DFR0524
However, the raspeberry PI 3 B + does not recognize the touch when it is connected to the USB (verified with the lsusb command).
I tried to connect other peripherals that are correctly recognized.
I use a 2.1A power supply to power the raspberry.
The USB cable with which I connected the touch screen works.
Can the display be defective or is there anything I can try to fix it?
Thank you
