That is not the issue. The Driver board get power input from the DC 12V/2A Power Adapter. The Driver board send digital signal out from its Micro-B ( for Touch) to the USB-A port of the Host (i.e. RPi, PC).
The Touch Monitor Kit includes 2 USB cables,
x1 USB-A to USB-C cable (for Power output to RPi-4)
x1 USB-A to Micro-B cable (for Touch signal output to the Host, i.e. RPi, PC)
In your case of using RPi-3 as Host, you will use the included USB-A to Micro-B cable (for Touch signal) and supply your own USB-A to Micro-B cable (for Power to the RPi-3).
Also for just in case, can you upload the /boot/firmware/config.txt from your RPi-3. If you put the microSD card in a Windows PC, it would the \firmware\config.txt file.
I would like to review the config settings to see if there is anything unusual.
I can't believe¡¡¡ works¡¡¡ is a cable fact¡¡¡¡ I change both Micro USB cable and now works perfectly¡¡¡
Thanks very very much and Merry Christmas. Asis
Perhaps those cables are for charging only, which has just the V+ (VBUS) and V- (GND) pins connected and not the D+ and D- pins that carry the data signal.
Because not all USB cables are created equal, I own a USB Cable Tester for checking all my different USB cable types that helped me on many occasions to troubleshoot usb cable related situations.
