• DUDU OS

  • Dudu7 no usb

I had to enable the Android developer settings in my device before USB media was recognized. try

Can you please tell me how to do it. I can find developer settings it says need subscription

Can't find developer mode

I figured it out but no luck. Shucks!

    Denny7 вы пробовали все входы USB? (одинарный USB, двойной USB, USb-C) Ни один из них не работает?

      Yes none will work. The c will charge my phone but no connection.

        Denny7 Can both single and dual USB be charged?
        Maybe you should try resetting the system

          I did a hard reset

          They charge for a sec then stop

          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.
