Hi Tiago,
Please provide the following information related to the issue:
- How are you trying to establish the connection for the mouse? What happens when you try to do so?
- Is the device getting detected under Device Manager?
The Microsoft Sculpt Ergonomic mouse is to be connected using the USB dongle/transceiver. You need to open the base of the mouse, take out the USB dongle, insert it into the USB port on the computer and then turn on the mouse using the power icon present
at the base.

Also, make sure that you download the driver/software (Windows 7) for the device from the link provide above in order to use the mouse. The device might show up when connection through the port under Devices list. But, you may not find it under Device Manager.
You may also connect the transceiver to a different USB port (either in the front or at the back panel) on the computer and check if you are able to use the mouse device.
