我有鼠标罗技 M505和键盘罗技 K340在同一个 USB 无线接收器上。我的 Ubuntu 是最新的。
问题是，有时候ubuntu 无法识别设备- 最近经常这样。我坐在登录屏幕前，什么也做不了。甚至闪烁的光标也停在欢迎密码字段。大多数情况下，硬重置是一种解决办法。
有时当我拔下 Logitech USB 接收器并重新插入时会有所帮助，等待大约 2 分钟并尝试按下键盘上的某些按钮。然后就有机会恢复这两个设备。
在我的 Windows 7 中一切正常。
系统详细信息如下：
Linux version 3.5.0-22-generic (buildd@komainu) (gcc version 4.7.2 (Ubuntu/Linaro 4.7.2-2ubuntu1) ) #34-Ubuntu SMP Tue Jan 8 21:47:00 UTC 2013
CPU: AMD Phenom(tm) II X6 1100T
syslog当我再次插入接收器时：

答案1
好的，我买了带有统一接收器的罗技 m525 无线鼠标，只是第二次发生这种情况，它突然停止工作了。
我想指出的是，这已经是第二次发生这种情况了，我第一次通过保修更换鼠标。
事实是，我将这只鼠标与我随身携带到工作场所的笔记本电脑一起使用，并且每天或多或少地在家使用它，因此每天大约（至少）有 2 次进/出循环。
更棒的是，我决定在这里写的原因是：如果你将统一接收器只插入 USB 插座的一半，它就会开始工作，所以问题是统一接收器由于不幸的使用频率不高而磨损了。也许这不是 Windows 的问题？
（如果您认为这是单个 USB 插座的问题，那不是，我的笔记本电脑上的所有 4 个 USB 插座都是这样）
