USB端口不再工作

Question

几天前，我曾试图将冷却风扇插入我的一个USB端口。令我沮丧的是，它没有起作用。我拔掉我的鼠标，把冷却风扇的插头放进去，它工作得很好，但是在另一个端口它没有改变任何东西。因此，出于困惑和好奇，我用鼠标的接收器替换了现在空的端口。它没有起作用。当我把它替换回通常的端口，并使用我的Xbox 360为冷却风扇供电后，我非常沮丧，现在这两个端口都没有工作。下面我将粘贴dmesg的输出，两个端口都是空的，然后我的鼠标插入一个端口，一个USB键盘插入另一个端口。如果我的dmesg输出错误，请通知我。

带有空端口的Dmesg输出：

现在.。有人能帮我吗？港口怎么了？是港口在物理上搞砸了吗？或者这是硬件问题？请帮帮我！

Answer 1

很有可能你在主板上烧了痕迹或者引爆了一根多丝保险丝。端口本身是相当耐用的，但你不能相信那些端口的高电流设备，如风扇。

这是硬件问题。冷却风扇从来没有被软件看到，而冷却风扇从来没有看到软件。它所做的就是从USB端口中拔出5 5VDC。
