A method, system, and computer-readable storage medium are provided for compressing a packet of data sent across a wireless transmission path to reduce power consumption in a wireless input device. The wireless input device preferably includes a human interface device that sends a report that is of variable length and compressed by refraining from transmitting unused bytes of a packet containing the report.

A report descriptor maintains the compresses format and provides that format, along with the compressed report, to the USB interface, for example, to recompile the standard report at the input port of, for example, a personal computer. The input device can be, for example, a keyboard and a pointing device. If a pointing device is used, the scroll wheel and button information can be combined into a single byte rather than utilizing two bytes as in conventional HID reports.
