A wireless interface device services communications between a wirelessly enabled host and at least one user input device. The wireless interface device includes a wireless interface unit, a processing unit, an input/output unit, and a power management unit. The wireless interface unit wirelessly interfaces with the wirelessly enabled host using a communication interface protocol. The power management unit operably couples to the wireless interface unit, the processing unit, and the input/output unit. The power management unit and the processing unit operate to control the power consumption of the wireless interface unit and the processing unit by powering down the wireless interface device and controlling the power consumption of the processing unit. The input/output unit remains powered to detect user input. When user input is detected, the wireless interface unit and processing unit are fully powered.
