[Bug 346883] Re: bluetooth applet unaware of pairing

This is not really a bug, or it may be a different sort of bug.

Apple firmware simulates the BT keyboard/mouse as USB devices; these are
then available after booting Ubuntu through the USB-HID interface
(they're listed when running the "sudo lsusb -v" command).
Unfortunately, not all functionality is available this way: the fn-key
on the keyboard; the scroll ball on the mouse.

In order for them to be treated as Bluetooth devices you must first
reset them with the command

$ sudo hciconfig hci0 reset

then (with a temporary USB keyboard/mouse attached) activate the
Bluetooth applet and let the BT keyboard/mouse be discovered and paired.
Keyboard fn-key and mouse scroll ball are now working, and the "sudo
lsusb -v" command does no longer list these devices.

Unfortunately, these BT pairings do not survive a reboot, not even when
the line

options hci_usb reset=1

is added to a file like /etc/modprobe.d/options.conf. That would be the
real bug...
