Filtered out unless you add the -a option. :)

The USB MIDI protocol doesn't allow runing status ...

... and here is one zero byte too much. Apparently, this device doesn't
conform to the USB MIDI specification.
Please uncomment the "#define DUMP_PACKETS" in line 58 or so of
sound/usb/usbmidi.c, recompile the snd-usb-audio driver, and show what
the driver writes to the system log when such note-on messages are
received. (Warning: the driver will dump all packets, including those
containing active sensing messages.)

You should be able to use any sequencer to connect a MIDI input port to
Windows' built-in software synth.
