Abstract
A computer accessory device—USB share is comprised of a multiplexer, which is connected to a computer host; a human interface device (HID) chip, which is connected to one output end of the multiplexer; a device output end, which is connected to another output end of the multiplexer; and a busyness detection module, which is connected to the middle of the HID chip and the device output end. The USB sharer may reach a sharing function of “N to 1” by applying N−1 sets of “2 to 1” sharer. Wherein, at least one “2 to 1” sharer's output end is connected to the device output end and, for other N−2 sets of “2 to 1” sharer, of which at least one output end is connected to the input end of another “2 to 1” sharers.
Claims20
A ┌computer accessory device—USB sharer┘ is comprised of:
- a multiplexer, of which the input side is connected to a host, and of which the output side is connected to an input side of another multiplexer;
- a human interface device (HID) chip, which is connected to one output side of the multiplexer;
- and
- a busyness detection circuit, which is connected to the middle of the human interface device chip and the device output side.
A ┌computer accessory device—USB sharer┘ achieves a “4 to 1” sharer with two sets of “2 to 1” sharer and another “2 to 1” sharer, wherein the output side of the two sets of “2 to 1” sharer is the input side of another “2 to 1” sharer, and an output side of another “2 to 1” sharer is connected to the device output side.
A ┌computer accessory device—USB sharer┘ achieves a “N to 1” sharer with N−1 sets of “2 to 1” sharer, wherein an output side of at least one “2 to 1” sharer is connected to the device output side, and the other N−2 sets of “2 to 1” sharer have an output side connected to the input side of another “2 to 1” sharer, wherein N is a positive integer that is larger or equal to 2.
