                    4b的板能不能接usb wifi6?
                    我接了RTL8852BU的wifi6的usb网卡
                    使用gst获取摄像头数据通过wifi发出去
                    gst会莫名其妙的出现gst_error(2)
                    我重新用gst再打开 过一会儿又出现了
                    如果不使用wifi发送使用有线就不会

                          @jugg 这模块还要做个小板转接才能使用?没有做好的USB接口的模组吗?或者RTL8822BU能否使用?

                                      @JohnConnor 没有标识型号。说免驱,一般都可以找到驱动支持

                                        4B板子的usb供电是多少的?
                                        外置usb wifi 需要1.2A的供电是不是会导致各自问题?
                                        比如系统崩溃、摄像头图像读不出来?

                                          @jugg 两个USB3.0接口各自1A的负载开关,两个USB2.0接口共用一个1A的负载开关。

                                            我用板子上的3.0接usb wifi
                                            4b099c42-1509-43d9-a884-6422e896c6bb-image.png

                                            这个周期性的超时 是不是因为供电不足
