Comment 14 for bug 1584475

I think this bug is affecting me as well. I am also aware of two other bug reports that sound related. Bug #1556444 and bug #1328065.

Skimming over the code in the patches I don't think those will work for me. The code specifically looks for this identifier string "FutureMax Dance Mat". My device reports itself with this string "RedOctane USB Pad". So I think the code won't treat my device any differently than the way it's being treated now.

kernel: [ 408.450782] usb 4-2.1: Product: RedOctane USB Pad
kernel: [ 408.460877] input: RedOctane USB Pad as /devices/pci0000:00/0000:00:1a.1/usb4/4-2/4-2.1/4-2.1:1.0/0003:054C:0268.0007/input/input19
kernel: [ 408.520387] sony 0003:054C:0268.0007: input,hiddev0,hidraw3: USB HID v1.11 Joystick [RedOctane USB Pad] on usb-0000:00:1a.1-2.1/input0

Here's my complete and utter beginner attempt at a modified version of the patch for the 4.8 kernel:

So, I'm going to attempt to produce an actual patch from this and see if it fixes my problem. Just wanted to drop this note here first and see if anyone comments. I've never done this sort of thing to the kernel code before so there's no telling how long this is going to take me.
