• DUDU OS

  • Dudu7 no usb

But do not recognize usb or 2k dvr

    Denny7 Do all USB harnesses come from DUDU? Or is there a USB connection to the original USB?

        dudu-lai all from dudu7

            Denny7 Did you do a system reset in Android Settings?

                dudu-lai yes

                    Denny7 Do you have a multimeter to measure the voltage?
                    Unplug the USB harness and measure the pins on the back of the mainframe to make sure you have 5V power supply

                        Ok I will tomorrow. One the 2k dvr the read light is on. When I plug my phone to the c usb it charges it but don't connect to it.

                          Denny7 I meant on the 2k dvr the red light comes on but no connection.

                            Denny7 какое подключение вы ждёте от телефона. Это не компьютер. Подключение телефона как накопителя не будет. Вы пробовали вставить usb flash drive?

                                Chubaka885 yes format it and tried usb drive no connection

                                  It was recognized by enabling external storage write permission in the developer options settings.

                                    lockc ok i will give it try Thanks!

                                      lockc no luck on that one thanks

                                            Sorry, i meant the back of the head unit 😊

                                              Ok will send after work

                                              JhonnyD

                                                Looks like the two usb plugs are not pressed deep enough into the port.

                                                Sometimes those plugs feels like they are plugged well but look at it.
