You will still get an error in a kernel driver if somebody else, even from
userland, has the interface open.

Can you dump the registry when your driver fails (i.e. Without repeating
your interface->open() call):

% ioreg -l > filename.txt

And include the complete portion for your device in an email to the list.
Also, please dump the info plist for your driver:

% pl < /path/to/your/kext/Contents/Info.plist
