Hi,
I have a G4 800 iBook with built in bluetooth adapter. I also have a Cube with a d-link dbt-120 bluetooth adapter. After upgrading the bluetooth firmware on the cube, the mouse now works in login panel and keyboard in open firmware etc. just like a USB mouse. Before upgrading, it didn't.
With my iBook, the bluetooth mouse won't work at login screen. It kicks in only when the desktop is fully loaded.
The question is: Should the bluetooth firmware update be applied also on the iBook?
BTW the bluetooth mouse on the iBook is the Microsoft one.
