I seem to be having the same problem with a Microsoft Sculpt Mobile Mouse I just bought.
http://www.microsoft.com/hardware/en-ca/p/sculpt-mobile-mouse This is in Xubuntu 14.04 amd64 on a Thinkpad W510. In the xfce "Mouse and Touchpad" settings I get two entries for "Microsoft Microsoft (R) Nano Transceiver v1.0".
