刚装完debian, 我的usb mouse 用不了了。

foil

比较奇怪，曾经有过一两次进系统后可以用。其中一次是刚装完9600显卡驱动。不过再重起就又不行了。具体症状为：启动时光鼠底下的光头是亮的，当屏幕上显示：ohci_hcd:Nvidia Corporation Usb Controller时有一小会停顿，然后鼠标光头就灭了。且再也不亮了。我又插了个ps/2的，用着没问题。
我的XFree86Config-4:
Section "InputDevice"

# Identifier and driver

    Identifier        "Mouse1"
    Driver "mouse"
    Option "rotocol"   "ImPS/2"
    Option "ZAxisMapping"   "4 5"
    Option "Device"     "/dev/input/mice"

# When using XQUEUE, comment out the above two lines, and uncomment
# the following line.

#    Option "rotocol"   "Xqueue"

# Baudrate and SampleRate are only for some Logitech mice. In
# almost every case these lines should be omitted.

#    Option "BaudRate"   "9600"
#    Option "SampleRate" "150"

# Emulate3Buttons is an option for 2-button Microsoft mice
# Emulate3Timeout is the timeout in milliseconds (default is 50ms)

    Option "Emulate3Buttons"
#    Option "Emulate3Timeout"    "50"

# ChordMiddle is an option for some 3-button Logitech mice

#    Option "ChordMiddle"

我试了/dev/psaux, 不好使。
