Checked into GIT the duplication of "mouse" for the Shuttle as Stefan recommended.  Also, modified and checked into GIT the change for the manual.  I tested on 3 different systems (new Fedora, older Fedora, 32-bit bullseye Debian) but never found any that called it mouse instead of if00, but it seems to work just fine with the duplication.  Not sure what the difference is but must have something to do with "plug and play" as the device gets created when plugged into the usb port.
