Fabrizio,

1. have you verified that you can manually load the kext using sudo kextload -t /System/Library/Extensions/YourCodeless.kext 2. If you copied the kext to /S/L/E, did you do touch /S/L/E and reboot. 3. You should try installing the IOUSBFamily log version and use the logging facility at level 6 to see which kexts were matched to the Logitech device.

The match criteria which you specify below will have the highest match priority.

best wishes.

Hello,
I ported g15daemon (a Logitech g15 leyboard driver using libusb) to
Tiger and it works fine using a codeless kext.
I'm not able to launch the same daemon on 10.5.x, it ends with libusb
errors (device handled exclusively by HID kernel module).
It seems that my codeless kext is not working properly.

This is the Info.plist (working on 10.4.x)
