Ok, tested a bit further. upstream kernel 3.15 generates the input events, but the event devices is only accessible for root.
But thats not a problem as there is also a js0 device which is picked up by stempania and works fine.

upstream kernel 3.17.0 generates some events, but these are spoty and
unreliable. The dancemat is not working in Stepmania.

evtest output: if one event appears, then there are huge repetitions of these 0 values which, from the name dose not make much sense for a dance pad, which has no orientation or analog positon x and y.

Title:
  No input events for FutureMax Dance Mat

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  On my ubuntu booth of my FutureMax Dance Mats does not generate any input events. So they can not be used. The hardware is working, i verified this with a windows PC.
  The missing events were checked with cat /dev/input/eventX, evtest, xev.

  On ubuntu the device is set up (udevadm has it, dmesg has it, evtest
  sees it), module joydev is loaded but no input is recognized/ visible
  and /dev/input/eventX

  Expected behavior: Plug and Play with the usb Dance Mat
  Acutal behavior: No play possible as no input events appear and so the game can not use it.
