问题
I am trying to detect whether a wireless mouse is present on a computer. I would like my program to run in the background. I would prefer to do this in Java however if this goes beyond Java's capabilities I can use another language.
Can someone please get me started?
(This seems like a Google-able question but I cannot find anything)

This is beyond Java and is highly OS-specific. You have to query the appropriate device drivers for the operating system; for example, on Linux this would mean looking up information in the evdev system. Note that the particular "type" of wireless will matter a lot, and you may not be able to tell in any reliable way. For example, a Bluetooth mouse is always wireless, but some wireless devices connect with a USB dongle and may not be distinguishable from a wired USB device.
