Re: Usb Digest, Vol 2, Issue 225

Is there some reason you are trying to do Isoch from a KEXT? Most of our Isoch clients (Audio, Video) are user-mode clients. Unless you need to provide services to an entity that lives in the kernel, you should probably consider doing all your work from user space.

As a KEXT, you are linked in with the kernel, and completion functions can be called directly.

Hi Mr.Ferguson,
    Thanks,I get it.
     But I have another problem.That is,
As you know,On application layer when we start
isoch reading we should create an event source
and add it to current RunLoop. When event comes
our callback function will be invoked.Is it the same
 in KEXT. If not, then how to do it.
   Thanks & Best regards.
