Thank you for solaar in Ubuntu.

I'm running solar on Xubuntu Precise, and I'm only getting 'Nano Receiver' as the only item in the main window. But the notification icon shows differently:

 Nano Receiver
 |-- Wireless Mouse M187

Because of this, I'm unable to do anything with the GUI, like view device properties, or pair/unpair devices.

Also, I'm seeing captured errors thrown by solaar in xsession-errors, if it matters:

Doesn't solaar support this Nano Receiver with usbid 046d:c52f?
