HID Device gets kidnapped by default mac driver

My Application wants to access a HID device I plugged in, but claiming the device does not work because its already claimed by IOHIDDevice Driver. In order to prevent that I learned, that I should create and install a codeless kext driver for mac(OSX 10.8.2) to blackbox my device from beeing loaded.

I spent two days already and I did not have any success so far. In my testcase you can find

It seems i cannot attach a file here.

Check into a code less KEXT to declare your device as available to user space apps.

It is essentially a plist.

For Yosemite and Mavericks, it needs to be signed by an Apple Developer ID approved for KEXT - you need to be a Developer and apply for that.

Depending on what level of access you require, HIDAPI http://www.signal11.us/oss/hidapi/ may provide you with what you need. It's a library that uses IOHidManager as a backend on OSX. Works for me on OSX 10.7.5, no dummy driver required.
