I am quite new to Arduino programming. I have a Arduino UNO and KEYES USB Host Shield, I am trying to connect the USB Host Shield to My PlayStation 4 Controller. It worked for a when i tested a few days back. But recently i tried again it wouldn’t work, I would like to ask if there are other ways to test whether the USB port of the shield can be tested with other methods in order to confirm that if it is working or not?
The library i used for the test : GitHub - felis/USB_Host_Shield_2.0: Revision 2.0 of USB Host Library for Arduino.
PS: while i used it a few days back i didn’t smell anything funny, soo… im guessing the board is not burn? plus the other i/o ports on the usb host shield is working fine. i just have trouble connecting the controller via usb.
I would really appreciate your help. thanks in advance!
