Comment 1 for bug 1556444

I believe I am also affected by this bug. I also think it may be related to or possibly even a duplicate of bug #1328065.

I have a RedOctane dance mat that has worked for years. It still works in fact. I have an older PC that I had been using it with to play stepmania. That PC is running Ubuntu 14.10. I stopped updating it years ago. The mat works as it always has with this PC.

I wanted to build a new stepmania machine with a somewhat newer machine I had laying around. I installed the current LTS release of Ubuntu 16.04 on that machine and everything works fine except the dance mat. The situation is nearly identical to what Smeuuh described above. I can see the mat being detected in the system log.

But no input is registered. stepmania recognizes that the device is connected but never detects my button presses. When I cat the corresponding device file there is no data written to my terminal when I press the buttons.

On the older machine running 14.10 I repeated all the and everything works normally. I see the dance mat show up in the system log just as I do on the machine running 16.04.

I have since tried on two other machines. I had another machine laying around, so I installed 16.10 on it. Same problem. An interesting twist. I also have a laptop that is running Ubuntu. 14.04 in this case. I see the same problem with the laptop as well.

So, the mat only works with the machine that is currently running 14.10.

The mat seems to be detected, but no input is registered on these Ubuntu variants: 14.04, 16.04, 16.10
