12.04 not detecting Apple Wireless Keyboard

Question

I'm having some issues pairing an Apple Wireless Keyboard with my Asus laptop running 12.04 and Win7. It does not have native Bluetooth, so I'm using a generic Rocketfish USB adapter.

I did get it to the PIN step, but mistyped and ended up cancelling.

Now, in the Setup New Devices, I notice that an entry flickers from time to time in the search box. But no entry ever shows up.

What I've done so far:

• sudo rfkill list shows that hci0: Bluetooth is not hard or soft blocked
• sudo hcitool dev prints out hci0 00:02:76:2E:5D:4F
• I installed the linux-firmware-nonfree package
• Batteries are not an issue, keyboard works when booted in Win7

During the search process, when I turn on the keyboard, the keyboard light stays lit for ~4 seconds or so and then goes out.

Any other solutions?
