原因是升级系统后，10.11增加驱动签名验证，导致IOUSBHIDDriverDescriptorOverride驱动不能正常加载。
关闭系统SIP功能后，键盘恢复正常。
但关闭SIP后，有一定的风险，自行评估。
1.Restart your Mac.
2.Before OS X starts up, hold down Command-R and keep it held down until you see an Apple icon and a progress bar. Release. This boots you into Recovery.
3.From the Utilities menu, select Terminal.
4.At the prompt type exactly the following and then press Return: csrutil disable
5.Terminal should display a message that SIP was disabled.
6.From the menu, select Restart.
