A brand new Magic Trackpad has been paired to a 2011 Mac mini with OSX 10.8. This mini has no other bluetooth devices. OSX was upgraded in-place from Lion to Mountain Lion.
The trackpad doesn't perform the gestures.
The Bluetooth menu shows that there's a mysterious bluetooth mouse device still as of yet unconnected. Various attempts to have it connect are unsuccessful. I suspect this is the gestures functionality, but it may be a previously connected mouse (unsure).
Various fixes attempted:
- reset PRAM with Cmd-Option-P-R at boot.
- reset SMC by pressing power when unplugged
How can I get this Magic Trackpad to be recognized by OSX Mountain Lion?
I don't have another Mac to try to reproduce this problem on (trying to determine if the trackpad itself is bad).

Your trackpad preference page is an earlier version than 10.8. I think 10.7 or before, so this is likely a software issue** The 10.8 page has changed a lot compared to your screenshot.
In the lower left it should say trackpad battery level and have battery icon with percentage. Having had some bluetooth problems in the past it should give you a battery level even if it is zero, unless the device is not completely paired, possible hardware issue.
With 10.8 under the Bluetooth preference page it will give you a list of all Bluetooth devices that have been paired with your machine, at the bottom below the devices should be a
+ -and a sprocket with a drop down menu that includes connect, rename, add to favorites, update name, update services, and show more info. The-will delete the selected device, I would suggest you delete the ghost mouse and maybe even the trackpad and try to pair the trackpad again. Also on the bluetooth page I have discoverable not selected.If you are running 10.8 and you have Apple Care I would contact Apple as your screen shot is showing an earlier version than 10.8 as far as I can tell.
