I have a chines DS4 clone and I was having the same issue. It seems that the feature 0x02 is not supported by it or something like that.

I don't know if this is required for something, but I have just commented out the function call from the penultimate line from the stack trace ( and added a pass in its place for function be valid in python) and it just works!

class HidrawBluetoothDS4Device(HidrawDS4Device):
    __type__ = "bluetooth"

    report_size = 78
    valid_report_id = 0x11

    def set_operational(self):
        #self.read_feature_report(0x02, 37)
        pass

Sorry I'm a noob in this, how do I make it work?

Hello, if you have exactly the same error, look for where the file hidraw.py is located in your error trace. Then, open it with a text editor (you may need to use sudo to be able to save it) and look for self.read_feature_report(0x02, 37). Comment out this line by putting a hash # symbol before the text. Finally, insert a line below with the text pass. Save the file, execute the program again and this error should be gone.

What we are doing here is disabling reading a characteristic not implemented in a chinese DS4 remote. The program will try to call the function but it will not do anything.

Keep in mind that this is Python, so in for the above to work, the pass word must have more indentation than def set_operational(self):
