            这个不用改可以直接用吗?
            你们有没有测试过?
            我试了好像有问题,ping经常超时 周期性的超时

                      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。
