前天我在ARM9之家淘宝店购买了的tiny4412 SDK开发板，S702电容屏，是最新的硬件和软件，同时我也购买了官网推荐的usb wifi(EOUP的) ，回来测试发现有如下的问题，请帮忙解答：
1.在android 5.0.2系统上插上USB WIFI后刚开始能正常连接上WIFI，运行5至10分钟后，WIFI连接断开，此USB WIFI就不起作用了，怎么搜索也搜索不到WIFI信号，重新启动后情况还是一样的，经过多次的测试都是这种情况，请帮忙看下原因，谢谢。
2.在linux + qtopia2.2.0中，插入此USB WIFI与android5.0.2 版本中的现象 一致，请帮忙 解答下呢。
说明，所购买的开发板均在是 ARM9之家淘宝店 购买的，软件都是光盘里的（最新的版本）。
tiny4412 购买的网址为：https://item.taobao.com/item.htm?spm=a1z09.2.9.20.K7GZsv&id=20151121169&_u=cae7bke9992
USB WIFI购买的网址为：https://item.taobao.com/item.htm?spm=a1z09.2.9.10.K7GZsv&id=14344502908&_u=cae7bkeb557

请帮忙看下，谢谢。

你好，我这也发现怎么也连不上WIFI的情况，串口打印出的信息如下：

然后android 5.0.2的wifi设置就一直显示connecting ，请帮忙 看下，若需要什么信息再跟我说下，谢谢。

。。。已经是完整的信息了啊，上面主要贴出来的是连接WIFI时串口打印的信息的啊。下面我把重启之后能够记录的log信息全贴出来了。

还有如果 是板子质量问题的话，我就直接退换货了，省得这么麻烦。。。

我们目前在考虑采用什么板子呢，主要是在做工厂的车间数据采集，确定好后会购买到大量的板子，如果你们友善的板子会有这种不稳定的问题且支持不够好的话，我们领导可能不会让我们批量采购你们的板子的。。现在在做技术上选型。

要说明的是我们目前在考虑采用什么板子呢，主要是在做工厂的车间数据采集，确定好后会购买到大量的板子，如果你们友善的板子会有这种不稳定的问题且支持不够好的话，我们领导可能不会让我们批量采购你们的板子的。。现在在做技术上选型。

根据提供的内核打印信息，没有看到usb设备的断开/连接的情况，也没有看到wifi设备的异常。
建议：
1) wifi突然断开后，先去android关闭wifi，再拨插usb wifi模块，再打开wifi，然后测试是否可以连接；
2) wifi断开后，可使用其它设备尝试扫描和连接wifi;
3) wifi突然断开时，在板上使用 logcat 获得日志以便进一步分析android；
4) 烧写linux来进行测试是否存在同样的问题，同时也收集kernel的日志以便分析;

根我初步分析 可能是板子质量有问题，USB WIFI 和有线网都不稳定。下面是USB WIFI由正常到掉线时的LOG，我没有移除USB WIFI，同时有线网络也出现无法使用的情况。出现这种情况后把USB WIFI拨了再插上去一点反映都没有串口也不打印数据的。

你们分析分析呢

从你新贴的2 个log 来看，usb 设备异常的断开了，从而导致Wi-Fi 和 Ethernet 出现异常，从内核打印的时间来看，大概10分钟就出现了
像这样的情况，我自己在使用Tiny4412的板子进行开发时还没有遇到过。
个人建议：
1) 可联系客服，看是否可以寄给他们进行检查并测试；
2) 详细的描述一下测试环境，有可能你测试容易遇到问题，但是当测试环境发生变化，可能就很难重现，因此详细的描述测试环境是利于定位并解决问题；
    a) 有没有连接LCD，是哪一种型号?
    b) 有没有连接其它的外设？比如HDMI
    c) 测试的网络配置是怎么样的
    d) 测试时，有没有仔细检查是否存在潜在的与其它硬件接触的情况
3) 有没有测试过多块板子？是否每块板都有同样的问题，建议将一这方面的信息一并反馈；
如果还有其它上面没有提到的，最好也能提供。遇到问题时，如果你提供的信息越多越全面，则会更有助于解决问题。
