Add support for the more rare volume usage which differs compared to the more common volume increment/decrement usages in which each volume change direction is represented using a distinct usage. The volume usage instead uses bits of the interrupt buffer to represent the wanted volume. The same bits should be within the bounds given by the logical min/max associated with the HID item. However, the volume is not interpreted as an absolute value but rather just looking at the sign bit in order to determine the volume change direction. I couldn't find any documentation of this usage and the implementation is therefore solely based on analysing actual data from Richard Toohey's <richardjtoohey at gmail dot com> Dell keyboard. |
