how to hot-replug the usb device?

Now I can send usb request command to the usb device,But I don\'t known how to do hot-replug like on windows os .

The IOUSBMassStorageClass is not sample code, but the actual code for the
USB Mass Storage Class driver that exists in Mac OS X which fully
supports USB storage devices with multiple logical units (look in the
file IOUSBMassStorageClass.cpp and the method BeginProvidedServices).

It may be easier for you to subclass your driver from
IOUSBMassStorageClass instead of trying to write an entirely new driver.

If your device is USB Mass Storage compliant, it should with work without
the need for you to write a driver.  Is there something unique about your
device that you need to support or a problem with the builtin
IOUSBMassStorageClass driver that is preventing you from using it?  

U may answer it for my previous question.any way,i will give u all score ,for i need it.

什么意思？不太理解，是要得到插拔的通知消息么？

1，in app  you can install a callback fuction,
2,in driver, please study the function table like window.

I can not give you source code, but I can tell you where you  go to find it.

usb DDK 中有一个 PDF文档，里面说得很详细。
具体用法可以参考 sample code.

APPLE USB DDK,你应该有吧？
