You are about halfway there. You need to create a code-less kext that
contains something similar to the following in its Info.plist:
<key>IOKitPersonalities</key>
<dict>
<key>MyMousePersonality</key>
<dict>
<key>CFBundleIdentifier</key>
<string>com.apple.iokit.IOUSBHIDDriver</string>
<key>IOClass</key>
<string>IOUSBHIDDriver</string>
<key>IOProviderClass</key>
<string>IOUSBInterface</string>
...
WHAT EVER YOU WANT TO MATCH ON
...
</dict>
</dict>
<key>OSBundleLibraries</key>
<dict>
<key>com.apple.iokit.IOHIDFamily</key>
<string>1.2</string>
</dict>
Make sure that you do not include the HIDDefaultBehavior key/value
pair. This is what tips off the HID Manager to drive the cursor.
In the future, I hope to have a mechanism to allow a trusted source to
accomplish this same kind of behavior via the HID APIs. Unfortunately,
this proves to be a security nightmare, and really need to be thought
out further.
Hope this works for you.

Hi everyone;
I have a usb device that shows up in the HID explorer, and I'd like to
get
data from it using HID. However, it seems to be classified as a mouse,
since when I press its button it sends out a mouse click. It does this
even if I have queued up that element using the HID Utilities library
and
am current reading data from it.
What I'd like to do is get the data via HID, but prevent the device
from
sending out actual mouse click events.
In the archives of this list there was mention of a way to prevent the
device from sending out the mouse clicks: I can make a vendor specific
driver to match my device exactly. I tried this and it works fine but
then it won't show up as a HID device because my driver matches it
exactly
so the HID driver doesn't get a chance.
Is there any way I can get the button clicks using HID but also prevent
the device from sending out a mouse click for each press?
thanks for your help!
