USB键盘偶尔工作
USB键盘偶尔工作
提问于 2012-07-06 09:17:45
几天前，我买了一个SL640 Hama USB键盘，用Ubuntu12.04在我的笔记本电脑上使用。但我有问题，因为它的工作时间是十分之一！
在我女朋友运行Windows的笔记本电脑上，这个键盘总是工作的。它也总是工作在我的笔记本电脑，当我启动到Windows 7，而不是Ubuntu。
以下是一些信息：
~$ lsusb
Bus 006 Device 003: ID 04d9:1503 Holtek Semiconductor, Inc. Shortboard Lefty如你所见，操作系统识别了它，但键盘没有反应.甚至连卡普斯锁和数字锁键都不会眨眼。
关于遗留支持(对GRUB有用)，我在BIOS中没有找到任何条目。但我对此不感兴趣。我只想在Ubuntu上使用它。
然而，在GRUB中，它有时起作用。
令人惊讶的是，现在我已经启动了我的笔记本电脑: usb键盘在GRUB中没有工作，但自从ubuntu登录后它就开始工作了！现在我用它打字。
好吧..。这意味着Ubuntu拥有正确的驱动程序，并且它们可以工作。但是，如何“加载”他们总是正确的？
下面是另一个例子：
经过几次即插即用操作后，现在它可以工作了。
下面是dmesg的输出：

我知道这个问题已经过时了，但对于那些仍然有这种麻烦的人(就像我一样)：
我也有类似的麻烦微软舒适曲线键盘2000。这个键盘有时突然挂起来，所以我不得不重新插上它。
我已经通过关闭irqbalance (就像Alen写的那样)和在启动时启用内核选项中的irqpoll来解决这个问题：(ubuntugeek.com解决方案)
gksudo gedit /etc/default/grub将GRUB_CMDLINE_LINUX设置为
GRUB_CMDLINE_LINUX=”acpi=force irqpoll”然后
sudo update-grub那就重新启动。

开放终端并输入：gksu gedit /etc/default/irqbalance
删除所有内容并粘贴如下：
#Configuration for the irqbalance daemon
#Should irqbalance be enabled?
ENABLED="0"
#Balance the IRQs only once?
ONESHOT="0"保存并重新启动。
