Ubuntu Feisty 内核 2.6.20，USB 鼠标，休眠 (suspend to RAM)后发生鼠标失去响应问题，每次要趴到地上重新插拔鼠标。
问题原因是休眠时内核的USB模块停止和重新载入出现问题。解决方法：
1. 确定USB有关内核模块，终端中运行
＃ lsmod | grep usb
我的显示如下：
usbhid 26592 0
hid 27392 1 usbhid
usbcore 134280 4 ohci_hcd,ehci_hcd,usbhid
2. 修改休眠脚本
＃ sudo vi /etc/default/acpi-support
找到如下内容，并将上面查到内核模块添加进MODULES 选项，如红字所示
# Add modules to this list to have them removed before suspend and reloaded
# on resume. An example would be MODULES="em8300 yenta_socket"
#
# Note that network cards and USB controllers will automatically be unloaded
# unless they're listed in MODULES_WHITELIST
MODULES="usbhid ehci_hcd ohci_hcd"
# Add modules to this list to leave them in the kernel over suspend/resume
MODULES_WHITELIST=""
3 保存退出,问题解决。
不解啊，还Note说USB已经自动卸载，莫非没有自动加载。
