Comment 19 for bug 1584475

I updated from linux mint 18 to 19, and I have a problem with this, a different one this time: my dance pad gets detected as a bogus accelerometer, and programs cannot use it. dmesg output is:

/dev/input/js0 reports periodic input, and gets detected by stepmania as an axis change. The actual input does not do anything. As root, I have in /dev/input/by-path/ the following:
pci-0000:00:14.0-usb-0:4.1:1.0-event pci-0000:00:14.0-usb-0:4.1:1.0-event-joystick pci-0000:00:14.0-usb-0:7:1.0-event

Of these, when I cat /dev/input/by-path/pci-0000\:00\:14.0-usb-0\:4.1\:1.0-event-joystick it does register input, although I have no idea how to make stepmania use that. The others are silent.

This is on Linux beta 4.15.0-29-generic #31-Ubuntu SMP Tue Jul 17 15:39:52 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
I cannot test other kernels because then my keyboard is non-functional for some reason.
