Re: Products without productID, what does that mean?

I have just noticed that on my 12" PB neither the trackpad nor the keyboard have a productID when I look at them with HID Device Explorer. Is that a "normal" practice? Why is this done? Is it only done for built-in hardware or does it also occur with external hardware? 

David,

The TrackPad and the internal keyboard on PowerBooks and iBooks are ADB devices, not USB device. ADB doesn't have productID.

Ah, that figures, I should have payed closer attention to the transport field. Are other (read external) ADB devices on older ADB Mac's or on USB Mac's with an iMate also mapped to HID manager devices on Jaguar? If so, is that only for mice and keyboards or also for gamepads and joystick?

Another question that comes to mind, would I be able in Panther to request exclusive access to a powerbook keyboard or trackpad when opening an interface? Or is that only possible for real USB devices.

Thanks,

david.
