I have a USB mass storage device (class 0x08, sub class 0x06).
For devices like this, typical the darwin kernel load automaticly
the own usb mass storage Kext.
Now I looking for a way, that the kernel should not load the default
driver. I want, that i can communicate with the device over IOUSBLib,
i.e. over IOUSBDevice class.
The MassStorage class is not required. I prefere to communicate with the
device directly from user space (without any own kext).
I mean, I need only a empty Kext-directory structure with a Info.plist
like:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd";>

<string>1.8.3b1</string>
<key>com.apple.iokit.IOUSBFamily</key>
<string>1.8</string>
</dict>
</dict>
</plist>
But this will not work. Whats wrong? Can somewhere give a hint?

Heiko
