Problems pairing Apple's Magic trackpad in 13.10

Hi,

Despite having search in the answers about pairing (problems with) Apple's Magic trackpad and having run through:

https://wiki.ubuntu.com/Multitouch/AppleMagicTrackpad

If you find that you are not being prompted to "Always grant access" and that the device is not available after a reboot (i.e., you have to reconnect), try adding the pincode for the device (0000) to /var/lib/bluetooth/<physical_device_ID>/pincodes, like so:

In a terminal:

Determine the physical (model-specific) and unique device IDs from the output of lsinput (from the "input-tools" package) as shown above.

Create /lib/bluetooth/<physical_ID>/pincodes as the root user (or with sudo):

 # This folder *should* already exist, create it with 'sudo mkdir' if not.
 # You can use TAB to complete, if it's the only Bluetooth device on your system:
 cd /lib/bluetooth/<physical_ID>

 sudo gedit pincodes
Add this line to the new file, save, and exit:
 <unique_ID> 0000
where <physical_ID> is a backslash-escaped physical device ID, like D8\:30\:62\:38\:18\:02, and <unique_ID> is your device's unique ID, both from the output of lsinput.

I don't get to succeed in pairing, let alone 'automatic pairing at login' of the Apple's trackpad!
Each time it tells me it failed!
Also it's strange to see that Apple's trackpad is recognized as 'tablet' and not as 'input device', seen the 'automatic pin' of 0000 should be filled in automatically. Whatever I do; it refuses to pair!

Can something be done about this? Until now in 13.10 I've (re)paired the trackpad (in dualboot 13.10 to OSX) each single time after login! There should be another (automatic) way I think....

Kind regards,

Ed
