How can I create a virtual HID device in code? I'm trying to avoid writing a kernel extension to accomplish this, but it seems to be the only way. I need to be able to create virtual HID devices of all types, and have an app running in the background feed them events. Is there a way to do this in user-space, or must I venture into kernel land?

A:
The typical way of creating HID devices is to use the IOHID* classes in IOKit. You can write a userclient that passes events in and out.
I'm not sure what a "virtual" HID device is, however, I guess. If you want to create a keyboard on the screen, that sort of thing can probably be done in userspace.

I mean an application that creates a HID device that doesn't really exist in the real world, but events can be passed to it over the network.

If it's an actual device you want to create, you need to do it in the kernel. If you want to simulate some sort of input, you may be able to do it in userspace.
